N/A The following specifications are generally applicable:
AMS 5630, QQ-S-763, ASTM A 276, ASTM A 580

N/A Used for severe abrasion service such as in needle valves, balls and seats for check valves and ball bearings. Well adapted for pump parts which must resist corrosion encountered in the oil industry.

N/A Type 440C resists corrosion from fresh water steam, crude oil, gasoline, etc., and resists staining from fruit and food acids. Maximum resistance is obtained by hardening and polishing.

N/A Resists scaling up to 12Q0°F in continuous service.

N/A Type 440C has fair machining characteristics, with a machinability rating of 40%, with 1212 rated as 100%. Surface cutting speed on automatic screw machines is approximately 65 feet per minute

N/A Poor welding properties, due to high carbon content.

N/A This grade has poor forming and stamping properties.

N/A Forge between 1900° and 2100°F, not below 1650°F. Cool slowly.

N/A Full annealing range is 1550°-1650°F. Cool slowly in furnace.

N/A Hardening range is between 1850° and 1950°F. Quench large sections in oil. Small sections may be quenched in air. Temper as required.
