Duplex stainless steel / MATERIAL REFERENCE
Hot-rolled lean duplex material with the EN 1.4162 comparison, practical guidance on its distinction from S32001, and clear fabrication and certification requirements.
HOT-ROLLED COIL, SHEET & PLATE
Sheye supplies this material as hot-rolled flat products. Confirm the required dimensions, heat treatment, surface and inspection basis for your order. Cold-rolled comparison values below are identified separately.
Compare the exact designation, chemical limits and test conditions before specifying material. Related grades are not automatically interchangeable or certified to all four standards.
EN 10028-7
Cast-analysis composition and solution-annealed, room-temperature flat-product properties. Sheye supply enquiries cover hot-rolled coil, sheet and plate; available dimensions are confirmed for each order.

Reference: A240/A240M-20aJIS G 4305
Cold-rolled stainless steel plate, sheet and strip. The requested Sheye additions are hot-rolled; JIS G4304 applicability must be treated separately.
Reference: 2021; current JSSA and Nippon Steel 2026 reference summariesSpecification confirmation requiredNo direct JIS G4305 or G4304 counterpart for S32101 was established from the reviewed JSA, JSSA and Japanese steelmaker primary sources. This means the direct correspondence is unverified, not a claim that no contractual Japanese specification can ever be agreed. JIS G4305 covers cold-rolled flat products. JIS G4304 is the separate hot-rolled flat-product standard; its scope alone does not establish grade coverage or numerical acceptance limits. Do not relabel SUS821L1, SUS323L or SUS329J3L as this grade merely because each is a duplex stainless steel.
GB/T 3280
Cold-rolled stainless steel plate, sheet and strip. Numerical values below are cold-rolled references; they are not acceptance limits for the hot-rolled products offered on this page.
Reference: 2015Mass %. ≤ means maximum; ≥ means minimum. A range includes both limits. “—” means no value published in this comparison; it never means zero.

ASTM A240 covers flat products; EN 10028-7 is for pressure-purpose flat products. JIS G4305 and GB/T 3280 cover cold-rolled flat products. Their cold-rolled values must not be used as acceptance limits for hot-rolled plate, bars or profiles. Confirm the standard edition and all supplementary requirements in the purchase order and mill test certificate.
Values are EN specification references, not automatic cross-standard equivalence, mill certification or universal as-hot-rolled guarantees. Width/direction-dependent yield minima are fully identified.
Use EN10028-7:2016 Table4 P≤0.035% and S≤0.005%. EN10088-1:2023 Table3 lists P≤0.040% and S≤0.015%, so copying general-purpose catalogue chemistry into this pressure-purpose row would be wrong. EN10028-7 Table4 permits Ni1.35–1.90%; its historic patent footnote describes the range up to1.70%. Do not narrow the standard chemistry to an Outokumpu typical value or an ASTM limit. LDX2101 is an Outokumpu grade/trademark reference; its appearance does not assert Sheye material was produced by Outokumpu. Only hot-rolled H/P room-temperature rows are selected for the requested product scope. A standard thickness maximum does not establish Sheye production capacity.
Chemistry is heat-analysis mass percent. Omitted elements have no requirement in the cited row, not zero. A480/A480M governs product-analysis tolerances and general requirements. Mechanical values use the printed SI column. ASTM regards SI and inch-pound systems as independent: do not convert ksi to generate an SI acceptance limit. Room-temperature Table 2 reference properties. Confirm delivery heat treatment, specimen preparation, dimensional tolerances and all general requirements against the contractual A480/A480M edition. Yield is based on 0.2% offset; a 0.5% total-extension-under-load alternative is permitted unless otherwise specified. Elongation gauge length is 50 mm or 2 in. HBW and the specified Rockwell scale are alternative permissible methods; thin-gauge superficial hardness provisions apply. The full 2026 numerical tables were not available for verification. Display the reference edition and confirm the contractual edition and certificate before accepting an order.
Heat-analysis mass percent from ASTM A240/A240M-20a Table 1. Omitted elements are not zero-content requirements; product-analysis tolerances are governed separately. ASTM A240/A240M-26 is the current official catalogue edition. These are explicitly 20a reference values; the complete 2026 numeric tables were not directly verified. Hot-rolled coil/sheet/plate must still meet the specified annealed delivery condition, surface, dimensions and inspection requirements. These tables do not establish Sheye production dimensions. No numeric grain-size grade or fixed ferrite/austenite percentage is specified for this grade in the cited A240 rows. Agree any microstructure or phase-balance acceptance criteria separately; do not impose the austenitic H-grade grain rule on duplex material. A480/A480M-22a §18.3 requires A923/A1084 testing only when ordered, with grade applicability to be checked. Do not claim that every heat has passed an intermetallic-phase test without a certificate. ASTM Table 1 printed p.4 and Table 2 printed p.9. Keep both thickness rows. Exactly 5.00 mm belongs to the higher-strength row under the printed SI condition. Annealing reference: A480/A480M-22a Table A1.2 minimum 1020°C, water quench or rapid cooling by other means; confirm the contract's incorporated edition. The C maximum is 0.040%, not 0.030%. Nitrogen, nickel, molybdenum and copper limits differ from S32001; the grades are not interchangeable solely because both are lean duplex.
JSA confirms the 2021 edition remains valid and was reaffirmed on 20 October 2025. Full purchased normative tables and all footnotes were not available for a complete current-edition audit. Listed chemistry is mass percent from primary JIS-grade summaries, not typical mill analysis. Missing cells mean not reproduced or not verified, not zero. Mechanical limits apply to the stated annealed/solution-treated cold-rolled condition at room temperature. Sampling, gauge length, direction, thickness-related rules and acceptance methods require the contractual standard. Corresponding designations are comparisons, not unconditional equivalence or proof that every supplied heat meets all listed standards.
No direct JIS G4305 or G4304 counterpart for S32101 was established from the reviewed JSA, JSSA and Japanese steelmaker primary sources. This means the direct correspondence is unverified, not a claim that no contractual Japanese specification can ever be agreed. JIS G4305 covers cold-rolled flat products. JIS G4304 is the separate hot-rolled flat-product standard; its scope alone does not establish grade coverage or numerical acceptance limits. Do not relabel SUS821L1, SUS323L or SUS329J3L as this grade merely because each is a duplex stainless steel.
Chemical composition is heat analysis, mass percent, from GB/T 3280-2015. The corresponding designation is a reference, not automatic cross-standard certification. The requested Sheye product is hot-rolled coil, sheet or plate. GB/T 3280 is a cold-rolled comparison only; confirm a hot-rolled order against GB/T 4237 or the other agreed hot-rolled product specification, including delivery condition and thickness-dependent tests. These standard reference properties do not state Sheye inventory, production dimensions, typical heat analysis or guaranteed cross-certification. Annex A compares S22294 with S32101. GB/T 3280-2015 sets Ni 1.35–1.70%; retain this exact GB row instead of copying a broader range from another national system.

SHEYE SUPPLY
S32101 is a nitrogen-alloyed lean duplex stainless steel with an austenitic-ferritic structure. It is considered for fabricated tanks, structural components and other equipment where strength, corrosion resistance and fabrication requirements must be evaluated together. The European comparison designation is 1.4162 / X2CrMnNiN21-5-1.
Enquiries can cover hot-rolled coil, sheets cut from coil and plate. Provide the component specification or drawing together with thickness, width and quantity. Include cut lengths for sheets and plates, or coil weight and handling requirements for coils. Available dimensions and delivery arrangements are confirmed against the enquiry.
S32001 and S32101 are separate lean duplex grades. S32101 has a different, higher nitrogen specification range, together with differences in the other alloying requirements. The EN comparisons are also different: 1.4162 for S32101 and 1.4482 for S32001.
A similar description or strength level does not establish that one can replace the other. Compare the applicable chemistry limits, product form, delivery condition and fabrication requirements. If substitution is proposed, it should be accepted against the project specification before the order is placed.
Specify the required ASTM or EN product standard and its edition. EN 10028-7 contains pressure-purpose flat-product requirements; EN 10088 covers a separate general-purpose specification route. Their published chemistry and mechanical requirements should not be combined into a single acceptance range.
For the EN 10028-7 comparison, solution-annealed condition, product thickness, material width and specimen direction matter. Mill datasheet values may describe a producer’s typical performance or specific guarantee; use the agreed standard and certificate requirements to define acceptance for the offered material.
Describe the working environment, planned forming and welding, and any surface treatment. Include slitting or cut-to-length requirements, edge quality, dimensional tolerances and surface protection. Request the necessary certificate type and specify how heat traceability must be preserved through cutting, marking and packing. These details help align material selection with the finished component and receiving inspection.
