SS Plate 309

Product Description

The SS Plate 309 are chromium-nickel austenitic stainless steel grades that are commonly used in environments with elevated temperatures. Due to their high chromium and nickel content, these grades of stainless steel plate are highly corrosive resistant and have outstanding resistance to oxidation as well as excellent heat resistance. 309 is an austenitic heat resistant alloy with oxidation resistance to 1900°F under constant temperature conditions. When frequent thermal cycling is involved, the alloy is resistant to about 1850°F. The offered SS Plate 309 are essentially nonmagnetic as annealed and become lightly magnetic when cold worked. They are very efficient.
