309S Stainless Steel

What is 309S Stainless Steel?

AISI 309S stainless steel (UNS S30908) is a high-chromium, nickel austentic alloy designed to perform in high-temperature and oxidizing environments.
It offers superior oxidation resistance up to 1100°C (2010°F) and maintains excellent mechanical strength at elevated temperatures.

The “S” in 309S stands for “Low Carbon”, making it more resistant to carbide precipitation during welding, similar to 304L. This makes 309S ideal for boilers, furnaces, kilns, exhaust manifolds, and heat exchangers.
