410 Stainless Steel Strip, Coil & Sheet

  • ASTM A240

410S Stainless Steel is a non-hardening modification of Type 410. A small aluminum addition minimizes austenite formation at high temperatures, thereby restricting the alloy’s ability to harden. The result is a soft, ductile condition when the material is rapidly cooled from above the critical temperature. This non-hardening characteristic also retards formation of hardening cracks when the steel is welded. The alloy is completely ferritic in the annealed condition.
