What are the mechanical properties of 42CrMo steel plate?

42CrMo steel plate belongs to alloy structural steel in terms of material classification. It has good mechanical properties and machinability, and is widely used. There are mainly two types of materials, plate and round bar. Its comprehensive performance is better than 40Cr, which has been recognized by the industry.

The mechanical properties of 42CrMo steel plate are as follows
Tensile strength σB (MPA): ≥1080 (110)
Yield strength σs (MPA): ≥930 (95)
Elongation δ5 (%): ≥12
Reduction of area ψ(%): ≥45
Impact energy Akv (J): ≥63
Impact toughness value αkV (J / cm2): ≥78 (8)
Hardness: ≤217HB

The results show that 42CrMo steel plate has high impact strength, high impact toughness and high impact toughness after multiple tempering. 42CrMo steel is suitable for manufacturing large and medium-sized plastic moulds requiring certain strength and toughness.
