Ferritic & low-carbon chromium grades / MATERIAL REFERENCE
A low-carbon chromium grade supplied under several stabilized specifications. Identify the exact Ti/Nb variant before ordering.
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
Stainless steel flat products for pressure purposes. Grade, product form, thickness and delivery treatment must match the standard. It is not a bar/profile standard.
Reference: 2016 (DIN EN10028-7:2016-10 current, checked2026-09-09)Specification confirmation requiredNo direct409L grade is established in EN10028-7:2016. Common EN1.4512 is not in its ferritic Table1; do not substitute1.4516 or1.4003 by name similarity.
ASTM A240/A240M
Plate, sheet and strip for pressure vessels and general applications. Flat-product reference data; not bar/profile specifications or guaranteed Sheye stock capability.
Reference: A240/A240M-20a reference tables (current catalogue: A240/A240M-26)Related-grade / reference qualifications applyJIS G 4305
Cold-rolled stainless steel plate, sheet and strip. These flat-product data do not establish a hot-rolled plate, bar or profile specification.
Reference: JIS G 4305:2021 grade references; steelmaker summaries and explicitly labelled 2012 mechanical rowsSpecification confirmation requiredA JIS G4305 SUS409L designation has not been established. Nippon Steel distinguishes its NSSC409L product from the similar SUH409L heat-resistant designation; SUH409L must not be presented as a verified G4305 row.
GB/T 3280
Cold-rolled stainless steel sheet, plate and strip, including slit wide strip. These values are not hot-rolled plate, bar or profile acceptance limits.
Reference: 2015Mass %. ≤ means maximum; ≥ means minimum. A range includes both limits. “—” means no value published in this comparison; it never means zero.

Rp0.2 is 0.2% proof strength; Rm is tensile strength; A is elongation. The delivery condition, product form, thickness and specimen basis belong to the value. Rows identify the reference specification or manufacturer summary and its qualifications; values are not design allowables.

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.
Chemical values are cast-analysis mass percentages. A dash/omitted element means no limit stated in the selected table, never zero content. Cross-standard grade names are comparison references, not automatic equivalence or proof of Sheye certification.
No direct409L grade is established in EN10028-7:2016. Common EN1.4512 is not in its ferritic Table1; do not substitute1.4516 or1.4003 by name similarity.
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.
The superscript L beside409 in the source is a footnote marker, not the name409L. S40900(Type409) has been replaced by S40910,S40920,S40930. The order and certificate must identify the variant; JIS/GB409L is not automatically equivalent.

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.
A JIS G4305 SUS409L designation has not been established. Nippon Steel distinguishes its NSSC409L product from the similar SUH409L heat-resistant designation; SUH409L must not be presented as a verified G4305 row.
Chemistry is heat analysis, mass %. The GB designation is a related reference, not automatic cross-standard certification. For thickness below 0.3 mm, elongation and hardness are reference values only. A50 is used at thickness ≤3 mm. Mechanical testing of re-rolling feedstock is performed when requested and specified in the contract (8.2). This is the Ti-stabilized GB reference. The purchase specification must identify the exact 409-family variant.

SHEYE SUPPLY
Sheye supplies 409L in coils, strips, sheets. Specify thickness, width or cut length, finish, quantity and the required delivery condition so the material and processing route can be reviewed together.
A low-carbon chromium grade supplied under several stabilized specifications. Identify the exact Ti/Nb variant before ordering. Specify the full grade designation and standard edition in the enquiry. Any dual-standard certification must be confirmed for the actual material.
Include the mill test certificate requirements, heat traceability, dimensional tolerances and any additional tests. For processed coils or strip, also state edge condition, coil inside diameter, coil weight and surface protection. Processing feasibility is reviewed against the material strength and dimensions.
