AISI 430 Stainless Steel

STEEL GRADE · STAINLESS 430

AISI 430 Stainless Steel

AISI 430 is a widely used ferritic stainless steel combining chromium-based corrosion resistance with low nickel content.

Grade overview

It is magnetic and generally not hardenable by conventional heat treatment. Formability is useful for many sheet applications.

Typical applications

Appliances, decorative trim, kitchen equipment, architectural interiors and automotive trim/exhaust-related components.

Equivalent / related designations

EN 1.4016 is a common comparison. Weldability and toughness can be more limiting than in austenitic grades.

Common manufacturers and supply

Produced in large volumes by major stainless flat-product 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.
