Heat Treatment And Annealing State 42crmo Steel Round Bar Shipping - China

42CrMo steel round bar delivery status: heat treatment state and annealing state

Implementation standard: GB/T 3077-2015

Its corresponding International Standard Organization brand: 42CrMo4

Corresponding Japanese brand: SCM440

Corresponding German brand: 42CrMo4 or 1 - 7225

Approximately corresponding to the US brand: 4140 or G41400 Mechanical properties of 42CrMo steel round bar The mechanical properties of 42CrMo steel round bar are excellent, and the following are its main indicators: Tensile strength (σb): usually between 1080~1220 MPa, indicating the maximum stress that the material can withstand during the stretching process.

Yield strength (σs): usually between 930~1080 MPa, which is the stress limit when the material begins to produce plastic deformation.

Elongation (δ5): between 11~17%, reflecting the plastic deformation ability of the material during the stretching process.

Sectional reduction rate (ψ): ≥45% or ≥55%, which indicates the percentage of the maximum reduction in the cross-sectional area at the reduced diameter after the material breaks under tension to the original cross-sectional area.

Impact toughness value (αkv): ≥78 J/cm², which measures the material's ability to resist fracture when subjected to impact loads.

Hardness: The maximum hardness can reach 55~60HRC, but the hardness will also vary after different heat treatments.
