|410S Stainless Steel Sheet/Plate:|
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.

- ASTM: A 240
- ASME: SA 240
- 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.
The alloy can not be hardened by heat treatment. It is annealed between 1600 – 1650°F (871 – 899°C), and then air cooled to relieve cold working stresses. 410S should not be exposed to temperatures above 2000°F (1093°C), due to embrittlement. If large grains are found after annealing mildly cold-worked material, the annealing temperature should be decreased to 1200 – 1350°F (649 – 732°C).
