416 Stainless Steel

Alro stocks 416 stainless steel - a hardenable chromium steel which elements have been added to improve the machinability and non-galling characteristics. This grade is magnetic in all conditions. Phosphorus and sulphur have been added to produce a free machining stainless steel. A wide range of mechanical properties may be obtained by conventional heat treating methods. 416 stainless is used for applications requiring good mechanical properties and involving corrosive conditions that are not too severe, such as valves and valve parts, machine parts, screws, bolts, pump rods, pistons, food industry machine parts, cutlery, etc. It can be turned, threaded, formed or drilled at speeds approaching those of screw stock. In the annealed condition, it can be drawn or formed. 416 is used for parts such as compressor shrouds, where oxidation resistance is required up to 1000 degrees F. Useful at high temperatures only when stresses are low. Maximum corrosion resistance of 416 is obtained by hardening and polishing. Manufactured by the electric-furnace process, it is a quality steel, free from all injurious defects, and meets the requirements of the aircraft industry.  Alro stocks 416 stainless steel in several bar shapes:  Round, Hex, and Flat.
