Hardness, Rockwell C: 22 HRC, Density: 7.85kg/m3
Tensile strength: 655 MPa .
Melting point: 1416°C
Thermal expansion: 12.2 µm/m°C (20-100 ºC)
Elastic modulus: 190-210 GPa (at 25 ºC ).
Forging of 4140 steel should be carried out between 2200 and 1650 º F (1200 and 900 º C). The lower the finishing temperature from forging, the finer will be the grain size. This alloy steel should ideally not be forged below 1650 º F (900 º C) and should be slow cooled after forging in Oil or water.
Slowly heat to 800～8500 ºC, keep enough time, ensure heat thoroughly. then cooling in furnace to 480 ºC, then cool in air. After annealing, the hardness 92 HBS Max.
4140 Steel is usually used at 18-22 HRc, If needs, AISI 4140 alloy steel can be hardened or Quenching by cold work. Quenching medium: oil
/ ℃ tempering temperature: 205 ~ 649°C.
After tempering hardness HRC: 18-25 HRc.
AISI 4140 alloy steel used for Structural products. As below:
Oil and gas sector, like collets, connection rods, conveyor pins, stem assemblies, gears, Bearings
Quality assured by Our ISO 9001:2008 quality management system. Our all AISI 4140 steel all had by SEP 1921-84 ultrasonic inspection (UT Test). Quality Grade: E/e, D/d, C/c.
