description
410S Stainless Steel Alloy Description:
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.

Additional Information on 410S
Alloy 410 stainless steel is a martensitic stainless steel grade routinely supplied in a hardened condition where high strength and moderate heat and corrosion resistance are required. 410S stainless steel is a low Carbon, non-hardening modification of Alloy 410 stainless.
Low Carbon plus a small amount of Titanium and/or Niobium minimize austenite formation at high temperatures restricting the ability for the alloy to harden. This keeps 410S soft and ductile even when cooled from above at critical temperature.
The non-hardening property helps to prevent cracking when the alloy is exposed to high temperatures or when welded.
410S is completely ferritic in the annealed condition, which means it has a body-centered cubic crystal making it less ductile than austenitic steel. It is used mainly for household utensils and other applications that do not demand high anti-corrosion properties. 410S has adequate corrosion resistance, much like 410, and good oxidation resistance.
