42CrMo steel for molds of bending machines

42CrMo steel belongs to the strength steel, with high degree and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering treatment, and good low-temperature impact toughness. The steel is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness.
 
42CrMo steel equivalent grades
China Executive Standard GB/T 3077-1999
It corresponds to the International Standards Organization brand: 42CrMo4
Corresponding Japanese brand: SCM440
Corresponding to German grades: 42CrMo4 or 1.7225
Approximately corresponding to American grades: 4140 or G41400
 
Scope of application
It has high creep strength and lasting strength at high temperature. 42CrMo steel is used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, pressure vessel gears, rear axles, loaded connecting rods and spring clips , Can also be used for oil deep well drill pipe joints and fishing tools under 2000m, and can be used for molds of bending machines, etc.
