Stainless steel 430 is a ferritic, straight chromium, non-hardenable grade, combining good corrosion resistance and formability characteristics with useful mechanical properties. Its ability to resist nitric acid attack permits its use in specific chemical applications but automotive trim and appliance components represents its largest fields of application. Alloy 430 has poor weldability compared to most stainless steels due to the higher carbon content and lack of stabilizing elements for this grade.
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.
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 Steel 416 is a corrosion resistant chromium steel alloy that is non-seizing, non-galling, free machining metal widely used in automatic screw machines. Its short brittle chips make it ideal for increased machining speeds, larger cuts, and longer tool life.
