Q:What is 309S stainless steel?
A:
309S (UNS S30908) is an austenitic heat-resistant stainless steel with approximately 23% chromium and 13% nickel. It is the low carbon version of 309, designed for high temperature applications with improved weldability and resistance to carbide precipitation.
Q:Why is 309S preferred over 304 for gas processing?
A:
309S has higher chromium (22-24% vs 18%) and nickel (12-15% vs 8%) content, providing superior oxidation resistance and high temperature strength compared to 304.
Q:What is the difference between 309 and 309S?
A:
The only significant difference is carbon content. 309S has lower carbon (<=0.08%) which minimizes carbide precipitation and improves weldability.
Q:What is the maximum part size you can machine?
A:
1500mm x 500mm x 500mm - suitable for large heat exchanger components, valve bodies, and furnace parts.
