4140 alloy steel forgings advantages

4140 steel forgings are alloy steel forgings containing high levels of chromium and molybdenum. 4140 alloy steel forgings have the characteristics of high strength, good hardenability, good toughness, and small deformation during quenching.

  1. High strength: The strength of 4140 steel forgings belongs to high-strength alloy steel forgings, with high yield strength and high tensile strength.
  2. Good hardenability: After quenching, 4140 steel has good hardenability and can meet the requirements of cooling rate.
  3. Good toughness: 4140 steel forgings have good toughness, can withstand large impact loads, and are not prone to cracks.
  4. Small deformation during quenching: 4140 steel forgings have little deformation during the quenching process and can be used to manufacture parts requiring high dimensional accuracy.
  5. High high-temperature creep strength and endurance strength: 4140 steel forgings have good strength and endurance performance at high temperatures.
