Heat Treatment of SAE/AISI 4140 Alloy Steel 4140 Steel Annealing Slowly heat to 8008500 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. AISI 4140 Steel Hardening & Quenching 4140 Steel is usually used at 18-22 HRc, If needs, AISI 4140 alloy steel can be hardened or Quenching
AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has lower tempering temperature. For example, tensile strength of 225 ksi cab be achieved by tempering at 316°C (600°F), and a tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F). 4140 forged steel round bar 42crmo,China 4140 forged steel Jul 25, 2012 · 4140 forged steel round bar 1)Strength to pull>=980(100)Mpa 2)Inspecting:ultrasonic test 3)Hardness=229HB DescriptionAlloy steel /Round bars(SAE 4135/35CrMo steel) ,rustInspectingultrasonic test according to SEP 1921-84 3C/cDelivery StateHot forged +Rough machined (black surface after Q/T)+ Turned ( as per customers requirementThe ProcessEAF + LF + VD + Forged + Heat Treatment
