42CrMo4 Steel Bar Hot Rolled Alloy Steel Round Bar with High Hardenability and Corrosion Resistance
42CrMo4 is an industrial material known for its super high strength, high hardenability, toughness, and absence of temper brittleness. This steel is used to manufacture forgings that require higher strength and larger quenched and tempered cross-sections than 35CrMo steel, including 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 offers superior material properties. EN 42CrMo4 alloy engineering steel materials have been widely used in automotive driving elements. Gnee Steel supplies prime quality 42CrMo4 alloy steel materials in a wide range.
