Stainless 317 is an austenitic chromium-nickel stainless steel with excellent corrosion resistance. (317 is a modified version of 316). Its high Molybdenum content enhances the grade’s superior pitting resistance. It is the most corrosion resistant of the 300 Series alloys and possesses the highest tensile and creep strength properties at elevated temperatures.
Stainless 422 is a hardenable, martensitic stainless steel with better strength at higher temperatures as high as 1200 F. It is capable of being heat treated to various high strength levels.
Alloy 321 (UNS S32100) contains increased titanium for improved strength and heat resistance, making it ideal for applications range of 800 – 1500°F (427 – 816°C). It has excellent resistance to intergranular corrosion. A popular aircraft alloy.
303 Stainless machines well and cuts clean and maintains it resistance to corrosion in temperatures up to 1500 degrees F. Good applications include repeat machining, fittings and fasteners.
