Carbon, Copper, and Nickel Steels
SSI Sintered Specialties
The iron-carbon, iron-copper, and iron-nickel steels are the “work horse” alloys of the PM industry. Designed for light to moderate loading, they are economical to process due to their ease of machinability, ease with which they may be pressed to moderately high densities, and their ability to be sintered effectively in a variety of atmospheres. These alloys may also be heat treated to improve strength and hardness, but due to their limited hardenability, must be heat treated with a secondary post-sintering process. Applications abound across numerous industries, including gears, pinions, sprockets, bearings, rotors, cams, flywheels, housings, levers, brackets, couplings etc. for automotive, motor cycle, hardware, lawn and garden, and other industrial markets.
