Oxidation Resistance
The oxidation resistance of 410S stainless steel is good. It can be used in continuous service up to 1300°F (705°C). Scaling becomes excessive above 1500°F (811°C) in intermittent service.
Formability
410S stainless steel can be easily formed by spinning, bending and roll forming.
