4140: The steel is made of alloy steel, which complies with the standard ASTM A29 / A29M-04
This product has high strength and high hardenability. Good toughness, small deformation during quenching, creep strength and long-term strength at high temperature. Used for forgings requiring higher strength and larger quenched and tempered sections than 35CrMo steel. Such as large gears for locomotive traction, supercharger driving this wheel, rear axle, connecting rods and spring clips under heavy load, can also be used for oil deep well drill pipe joints and fishing tools below 2000m
