1: Brief Introduction Of 410S stainless steel  
Alloy 410S (UNS S41008) is a low carbon, non-hardening modification of Alloy 410 (UNS S41000) the general purpose
12% chromium martensitic stainless steel. The low carbon and a small alloy addition minimize austenite formation at high
temperatures which restricts the alloys ability to harden. 410S remains soft and ductile even when rapidly cooled from
above the critical temperature. This non-hardening characteristic helps prevent cracking when the alloy is exposed to
high temperatures or welded. 410S is completely ferritic in the annealed condition. It exhibits adequate corrosion resistance
similar to 410 and good oxidation resistance.
Oxidation Resistance:
*Good oxidation resistance
*Can be used in continuous service up to 1300°F (705°C).
*Scaling becomes excessive above 1500°F (811°C) in intermittent service.
Corrosion Resistance:
*Corrosion resistance of 410S stainless steel is similar to type 410.
*Resists corrosion in atmospheric conditions, fresh water, mild organic and mineral acids, alkalis and some chemicals.
*Exposure to chlorides in everyday activities (e.g., food preparation, sports activities, etc.) is satisfactory when proper
cleaning is performed after exposure to use.
