410 stainless steel composition and characteristics

Semi-martensitic stainless steel has high strength and toughness after quenching and tempering, and has good corrosion resistance and machining properties in weak corrosive media with a temperature of not more than 30 degrees. In the wet atmosphere, fresh water conditions also have rust resistance and corrosion resistance, and have high thermal stability below 700 degrees. Good machinability but poor machinability and weldability.
