Austenitic and 400-series rows are ASTM A240 / producer product limits; rows marked † and 254 SMO are producer nominal chemistries shown for comparison. Iron is balance. S31803 is not automatically S32205 (S31803 permits Cr 21–23, Mo 2.5–3.5, N 0.08–0.20). For 347, "Cb" is columbium — the historical name for niobium. Final chemistry is confirmed on the heat-wise MTC (EN 10204 3.1).
Grades, UNS & EN Equivalents
| Grade | UNS | EN / producer ref | Note — cross-reference, not automatic substitution |
|---|---|---|---|
| Austenitic | |||

| 301 | S30100 | 1.4310 | High work-hardening; cold-worked tempers have their own strength rows. |
| 304 | S30400 | 1.4301 | Most common 18-8; compare full ordered requirements. |
| 304L | S30403 | 1.4307; 1.4306 (some producers) | Two EN compositions exist — "304L" alone does not choose between them. |
| 316 | S31600 | 1.4401; 1.4436 (higher-Mo) | Producer variants must keep their identity. |
| 316L | S31603 | 1.4404; 1.4435 (higher-Mo) | Not a universal one-to-one equivalence. |
| 316Ti | S31635 | 1.4571 | Ti-stabilised; compare stabilisation and delivery requirements. |
| 317L | S31703 | 1.4438 | Higher Mo than 316L; not 317LMN. |
| 321 / 321H | S32100 / S32109 | 1.4541 / 1.4940 | H is a separate grade; keep EN and historical DIN distinct. |
| 347 / 347H | S34700 / S34709 | 1.4550 / 1.4912 | Nb-stabilised for high-temperature service. |

| 310S | S31008 | 1.4845 | Not 1.4841; the high-Si 314 / 1.4841 comparison differs. |
| 904L | N08904 | 1.4539 | Super-austenitic; current pipe/bar specs are A312 / A269 / A479, not the older B677 / B649. |
| 254 SMO | S31254 | 1.4547 | 6Mo super-austenitic; 1.4529 is only a nearest comparison, not identity. |
| Duplex & Super Duplex | |||
| 2304 | S32304 | 1.4362 | Lean duplex, distinct from 2205. |
| 2205 | S31803 / S32205 | 1.4462 | Keep the two UNS acceptance definitions separate. |
| 2507 | S32750 | 1.4410 | Not the same UNS as S32760. |
| Zeron 100 | S32760 | 1.4501 | Cu/W-alloyed super duplex; branded chemistry can be tighter than base UNS. |
| Ferritic | |||
| 409 | S40900 / S40920 | 1.4512 | Confirm the actual UNS variant; legacy and low-interstitial 409 differ. |

| 410S | S41008 | 1.4000 | Low-carbon, non-hardening variant. |
| 420 | S42000 | 1.4021 / 1.4034 (by carbon) | A single EN number is inadequate — specify carbon band and condition. |
| 431 | S43100 | 1.4057 | High-strength martensitic; condition-dependent properties. |
| Precipitation-Hardening | |||
| 17-4PH | S17400 | 1.4542 | Specify aging condition (e.g. H900 / H1150) and product form. |
| 15-5PH | S15500 | 1.4545 / 1.4540 (producer refs vary) | Confirm the producer EN reference before substitution. |
| 17-7PH | S17700 | 1.4568 | Semi-austenitic PH for springs and formed parts. |
EN / Werkstoff numbers are cross-references, not automatic substitutions — chemistry, properties, condition and testing can differ. Identify the product specification, not just the steel number. Specialist grades (free-machining 303/416, 314, 348, 440A/B/C, 6Mo N08367, lean duplex S32101) are supplied against a separately verified datasheet.

Duplex seamless tube/pipe — producer solution-annealed (A789/A790 context)
| Grade | Rp0.2 min MPa | Rm MPa | A min % | Hardness max |
|---|---|---|---|---|
| 2304 | 400 | 630–820 | 25 | 30 HRC |

| 2507 | 550 | 800–1000 | 25 | 32 HRC |
Flat-product minima follow ASTM A240; duplex values are producer solution-annealed references for stated wall ranges — never merge the two bases. Precipitation-hardening grades are condition-dependent: 17-4PH in H900 reaches roughly UTS ≥ 1310 MPa, 0.2% yield ≥ 1172 MPa, elongation ≥ 5% at 40–47 HRC; other conditions (H1075, H1150) differ. Always specify the final heat-treatment condition.

| 430 | 7.7 | 220 | 25 | 460 | 10.0 (20–100°C) | 0.60 |
Representative producer reference values at 20°C unless noted — not acceptance limits or design allowables. 310S expansion is quoted over 20–600°C, so do not compare it directly with the 20–100°C rows. Austenitic grades are essentially non-magnetic when annealed; 410 and 430 are magnetic.
Specifications & Product Forms

|---|---|---|
| Austenitic pressure pipe | ASTM A312 (seamless/welded); A358 (EFW, by class) | ASME B36.19M, or explicitly ordered B36.10M |
| Duplex pipe | A790 (seamless/welded); A928 (EFW with filler) | Exact UNS, weld class, heat treatment, examination |
| Boiler / heat-exchanger tube | A213 (seamless); A249 (welded) | Actual OD × wall, wall basis, length |
| General / hygienic tube | A269 (general); A270 / ASME BPE (hygienic) | OD × wall, surface finish / Ra where specified |
| Butt-weld fittings | A403 (austenitic); A815 (duplex/ferritic/martensitic) | ASME B16.9 or MSS SP-43; grade, class, exam |
| Forged flanges & fittings | A182 (e.g. F304L, F316L, F51/F53 duplex) | B16.5 (½–24"); B16.47 Series A/B (26–60"); B16.11 |
| Plate, sheet, strip | A240 with A480 general requirements | Thickness, width, finish, flatness, edge |

| Bolting | A193 (B8/B8M) with A194 nuts; A320 low-temp | Grade, class, size, treatment — not plain 304/316 values |
A213 is a tube specification (OD × wall), not a pipe schedule standard. A schedule is a wall designation, not a pressure rating. MSS SP-75 concerns high-strength wrought BW fittings and is not a general substitute for A403 / B16.9.
Corrosion & Temperature Selection
| Service | Guidance |
|---|---|
| Chlorides & seawater | 316/316L improves on 304 through molybdenum but is not seawater-proof; high-chloride duty typically moves to 6Mo (254 SMO), super duplex (2507 / S32760) or qualified duplex. |
| Acids & process chemicals | 316L, 317L, 904L and 6Mo selected by acid type, concentration, impurities, temperature and aeration — not simply by higher alloy content. PREN is a comparative index, not a lifetime guarantee. |
| High-temperature & cryogenic | No universal maximum temperature — separate oxidation resistance (309S, 310S, 314) from code allowable stress, creep and time. H and stabilised grades serve pressure duty; austenitics offer good cryogenic toughness subject to code rules. |
| Sour service | Distinguish NACE MR0175 / ISO 15156 (H₂S production) from MR0103 / ISO 17945 (refining); qualification is service-, condition-, hardness- and grade-dependent. |
Welding, Forming & Surface Treatment
| Family / step | Guidance |
|---|---|
| Austenitic 304/316 | Generally weldable with a qualified procedure; L variants reduce sensitisation. Manage distortion, work hardening, shielding/back purge and heat-tint removal. |
| Duplex & super duplex | Control heat input, interpass temperature, cooling and filler to keep the ferrite/austenite balance; qualify with the applicable phase and corrosion tests. |
| Ferritic, martensitic & PH | Grade-specific rules — grain growth (ferritic), hydrogen-cracking risk and preheat/PWHT (martensitic), condition control (PH). Not a family-wide "excellent weldability" claim. |
| Surface treatment | Heat-tint/scale removal (pickling/descaling, ASTM A380) and passivation (A967) are related but different operations. Distinguish mill finishes (2B, 2R) from measured Ra. |
| Free-machining 303/416 | Machine well through sulphur additions but have reduced weldability and can show lower corrosion resistance — not routine substitutes in welded service. |
Testing, Traceability & Documentation
| Item | What to specify / know |
|---|---|
| MTC / traceability | Heat identity on the certificate must match product markings; distinguish heat analysis from product analysis. |
| EN 10204 3.1 vs 3.2 | 3.1 is validated by the manufacturer's authorised representative; 3.2 adds validation by a purchaser- or regulation-designated inspector — agree the plan before supply. |
| PMI | Specify method and elements. Handheld XRF cannot measure carbon, so it alone cannot distinguish standard-carbon from "L" grades. |
| IGC / duplex phase | ASTM A262 (austenitic) is a family of practices; A923 / A1084 for duplex where specified — state method and grade coverage. |
| Pitting & hydro/NDE | G48 or agreed pitting test needs method, temperature and acceptance; hydro/NDE follow the ordered product specification and class. |
Applications, Industries & Grade Guidance
| Application | Grades commonly considered | Constraints to state |
|---|---|---|
| General process, food & water | 304L, 316L | Chemistry, chlorides, temperature, hygiene design, finish |
| Pharmaceutical / hygienic tubing | 316L (A270 / BPE where specified) | Ra, electropolish if ordered, weld quality, validation |
| Chemical & process piping | 316L, 317L, 904L, 6Mo (by medium) | Acid type/concentration, impurities, temperature, aeration |
| Seawater / desalination | 6Mo, 2507 / S32760, selected duplex | Crevices, chlorination, temperature, velocity, galvanic coupling |
| Offshore / production piping | 2205, super duplex or qualified alloy | Chlorides, H₂S/CO₂, mechanical duty, sour-service qualification |
| Boilers / refinery hot lines | 304H, 316H, 321H, 347H | Creep/rupture, grain size, heat treatment, code allowables |
| Furnace parts / oxidising heat | 309S, 310S, 314 | Oxidation, carburisation, thermal cycling, load — not a pressure rating |
| Valves / shafts / pumps | 410, 420, 431, 17-4PH, 15-5PH | Heat-treatment condition, toughness, hardness, sour-service limits |

Frequently Asked Questions
What is the difference between 304 and 316 stainless steel?
316 normally contains specified molybdenum additions that improve resistance to pitting and crevice corrosion relative to 304 in many chloride environments. Neither is universally suitable for seawater or every chemical — selection depends on temperature, concentration, crevices and cleaning conditions.
When should I specify 304L or 316L?
The low-carbon variants limit carbon to 0.030% maximum under common specifications and reduce weld-related sensitisation. They do not eliminate all corrosion mechanisms, so use the exact product specification and required mechanical properties.
Is Schedule 40S the same as Schedule 40?
Not at every size. The S-series belongs to ASME B36.19M; other walls may be ordered to B36.10M. Compare the actual OD and wall for the required NPS — a schedule number is a wall designation, not a pressure rating.
Can PMI confirm 304L or 316L?
Handheld XRF does not establish carbon content, so it cannot by itself distinguish standard-carbon from L grades. Require the MTC and a method capable of measuring the necessary elements when verification is specified.

The low-carbon variants limit carbon to 0.030% maximum under common product specifications and reduce susceptibility to weld-related sensitisation. They do not eliminate all corrosion mechanisms, so use the exact product specification and required mechanical properties.
Are 304 and 304L, or 316 and 316L, interchangeable?
Not automatically. Material may be dual certified only when it satisfies all requirements of both ordered designations. A low-carbon chemistry result alone does not establish dual certification or high-temperature suitability.
Are EN and UNS grades exact equivalents?
Cross-reference tables are selection aids. Chemistry, mechanical properties, delivery condition, product scope and testing may differ, so substitution requires a documented comparison and purchaser or design approval.
Is Schedule 40S the same as Schedule 40?
Not at every size. The S-series belongs to ASME B36.19M; other dimensions may be ordered to B36.10M. Compare the actual OD and wall for the required NPS. A schedule number is a wall designation, not a pressure rating.
What is the difference between pipe and tube?
Pipe is commonly ordered by NPS and schedule; tube is commonly ordered by actual OD and wall thickness. Their applicable standards, tolerances and tests differ.
Which stainless steel is suitable for high temperatures?
Selection must consider oxidation, creep strength, allowable stresses, exposure duration and atmosphere. H grades, stabilised grades and heat-resistant grades serve different purposes; a producer oxidation-temperature figure is not a pressure-design limit.
Can PMI confirm 304L or 316L?
The test method matters. Handheld XRF does not establish carbon content, so it cannot by itself distinguish standard-carbon from L grades. Require the MTC and a method capable of measuring the necessary elements when verification is specified.
Can Sagiant provide inspection documents and special testing?
Specify the EN 10204 document type, traceability, PMI method, inspection hold points and special tests with the enquiry. The quotation confirms the agreed document and inspection scope based on the material, standard and project.
What information should I include in an RFQ?
State product form, standard and edition, grade/UNS, dimensions, quantity or length, condition/finish, ends or flange details, design service, certification, testing and delivery location. For tube add OD and wall basis; for flanges add class, facing and applicable series.
