Grade overview

Lower carbon improves resistance to weld sensitization while maintaining the Mo-bearing corrosion performance of the 316 family.

Typical applications

Process piping, tanks, pharmaceutical and food equipment, desalination auxiliaries, chemical equipment and welded stainless fabrications.

Equivalent / related designations

Commonly compared with EN 1.4404. Final material choice should consider chloride concentration, temperature and cleaning chemicals.

Common manufacturers and supply

Available globally from leading stainless plate, coil, bar and pipe producers.

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.
