309/309S Stainless Steel Grade:
Heat uniformly at 1742 – 2192°F (950 – 1200°C). After hot forming a final anneal at 1832 – 2101°F (1000 – 1150°C) followed by rapid quenching is recommended.
309/309S Stainless Steel Grade:
Cold forming of pieces with long-term exposure to high temperatures is not recommended since the stainless steel is subject to carbide precipitation.
309/309S Stainless Steel Grade:
It can be welded by most standard processes, including TIG, PLASMA, MIG, SMAW, SAW and FCAW.

What Is The Difference Between 309 And 309S?
Answer:
309S is an extra-low carbon variant of 309. Due to a lower carbon content, that minimizes carbide precipitation and improves weldability.
What Is Stainless Steel?
Answer:
309/309S is one of the stainless steel grade. Grades of steel that contain more than 10 percent chromium — with or without other alloying elements — are called stainless steel.
How Does Chromium Prevent Rusting?
Answer:
309/309S stainless steel contains chromium (22.0 min.-24.0 max). Chromium and other elements react with air and water to form a thin film on the outside of the steel. This film serves as a barrier that prevents corrosion.
