Type 309S stainless steel is a low carbon version of Type 309. Because of its lower carbon-content, Type 309S minimizes carbide precipitation, and improves weldability. Other key properties of Type 309S include:
It can be easily roll formed, stamped and drawn
Higher resistance to marine atmospheres than Type 304
Good weldability and machinability
Outstanding resistance to oxidation
