Essential details
Alloy 309/309S (UNS S30900/S30908) austenitic stainless steel is typically used for elevated temperature applications. Its high chromium and nickel content provides comparable corrosion resistance, superior resistance to oxidation, and the retention of a larger fraction of room temperature strength than the common austenitic Alloy 304.
Application:
- Industrial furnaces
- Annealing bells
- Heat exchangers
- Salt bath treatment equipment
- Calrods
