Grade overview

It is a chromium stainless with moderate corrosion resistance and higher attainable hardness than austenitic stainless grades.

Typical applications

Valve parts, turbine components, shafts, fasteners, cutlery and general wear-resistant stainless parts.

Equivalent / related designations

EN 1.4006 is a common comparison. Heat-treatment condition has a major effect on strength, hardness and toughness.

Common manufacturers and supply

Produced by stainless bar, plate and specialty steel mills globally.

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. Requirements vary by standard edition, product form and manufacturer; verify the latest governing specification.
