We combined with many years of practical experience and developed a series of forged alloy steel, 1.3401 High Manganese Steel Plate, skd11 specification. In the fierce market competition, our company image has penetrated into all fields of society. We promise to satisfy every owner. Since its establishment, our company has adopted advanced management methods, strictly controlled the channels of purchasing goods, reduced the cost of customers and made the company enjoy a good reputation.
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
