High Quality Aisi 4140 Tensile Strength Wholesale Purchase - China

The tensile strength of AISI 4140 steel varies according to different heat treatment states:

- In the annealed or normalized state, the tensile strength of bars with a diameter of less than or equal to 12.7mm generally does not exceed 862MPa (125ksi).

- After quenching and tempering, the tensile strength of AISI 4140 steel can reach about 850-1000MPa, or even higher.

- Under certain tempering conditions, such as tempering at 316℃, the tensile strength can reach about 1550MPa (225ksi); when tempered at 538℃, the tensile strength is about 900MPa (130ksi).

- The high-strength AISI 4140 steel used for fasteners has a tensile strength of less than 1379MPa and a hardness of less than 50HRC, which is suitable for manufacturing high-strength bolts, screws, etc.

In summary, the tensile strength range of AISI 4140 steel is roughly between 655MPa and 1379MPa, and the specific value depends on its chemical composition, heat treatment process and application requirements.
