Grade overview

An 18Cr-8Ni-type stainless family with good formability, weldability and toughness. Exact chemistry depends on the governing ASTM/EN/JIS specification.

Typical applications

Food equipment, tanks, architectural components, piping, kitchens, general process equipment and fabricated stainless products.

Equivalent / related designations

EN 1.4301 and JIS SUS304 are commonly compared designations, but product standard and mechanical requirements must also match.

Common manufacturers and supply

Produced globally by Outokumpu, Acerinox, Aperam, POSCO, Jindal Stainless, Tsingshan, TISCO/Baowu and other stainless mills.

Fabrication and selection notes

Confirm the exact product standard, edition, dimensions, delivery condition, mechanical properties, impact requirements, heat treatment, welding procedure, corrosion environment and certification. A grade name alone is not sufficient for procurement or design approval.

QA/QC documentation

For critical service, verify heat number traceability, mill test certificate, chemical analysis, tensile/impact results where required, NDT, heat-treatment record and project-specific third-party inspection requirements.

Element Folio engineering reference. Values and requirements vary by standard edition, product form and manufacturer; always verify the latest governing specification.
