Product Description

42crmo4 Steel Bar 42crmo4 Steel Rod Hot Rolled Alloy Steel Round Bar

42crmo4 is an industrial material. 42CrMo4 steel is super high strength steel with high hardenability and toughness and it has no temper brittleness.42CrMo4 is used to manufacture forgings that require higher strength and larger quenched and tempered cross-sections than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and spring clamps under extreme load.


Although 42CrMo4 steel is more expensive than 41Cr4 steel, it is more preferable in terms of material properties. EN 42CrMo4 alloy engineering steel materials have been widely used in automotive driving elements. Gnee Steel is able to supply you prime quality of 42CrMo4 alloy steel materials with wide range.
