Type 416 is a chromium grade of stainless steel modified by the addition of phosphorus and sulphur to produce a free machining steel. lt is the most readily machinable of all stainless steels. A wide range of mechanical properties may be obtained by conventional heat treating methods. It is magnetic in all conditions.

Applications: Type 416 is used for applications demanding the mechanical properties and corrosion resistance of Type 410 combined with free machining properties. It can be turned, threaded, formed or drilled at speeds approaching those of screw stock.

Corrosion Resistance:Excellent resistance to corrosion from atmosphere, fresh water, food acids and neutral and basic salts. This grade has excellent corrosion resistance in all conditions of heat treatment, but maximum resistance is obtained by hardening and polishing. In general, corrosive resistant qualities are slightly less than those of Type 430.

Resistance To Scaling:Resists scaling at temperatures up to approximately 12O0-1300 Deg. F in continuous service.

Hardenability: A 3/8" section quenched in oil from 1825 Deg. F will harden to a minimum of Rockwell 'C' 35.

Machinability:Type 416 has very good machining characteristics. It has a machinability rating of approximately 91% with B-1112 rated 100%. Surface cutting speed on automatic screw machines is approximately 150 feet per minute.

Weldability:This grade has poor welding properties. Welds are brittle, with tendency to crack.

Forging:Forge between 2100 and 2300 Deg. F Do not forge below 1700 F. Cool slowly.

Annealing:Full annealing range is between 1550 and 1650 Deg. F. Cool slowly in furnace. Low annealing range is between 1200 and 1400 Deg. F. Cool in air.

Hardening:Hardening range is between 1750 and 1850 Deg. F Quench large sections in oil. Small sections may be quenched in air. Temper to required hardness.
