Sichuan Liaofu Special Steel Company is one of the most experienced manufacturers and suppliers of 1.2379 steel flat bar d2 flat bar in China. With over 20 years' experience, our factory offer high quality products made in China with competitive price. Welcome to contact us for wholesale service.
1.2379 Steel Flat Bar D2 cold working die steel - Uses: 1) Suitable for complex and possibly deformed tool steel, high wear resistance and long life of all kinds of cold stamping die and cold cutting blade, rolling wire plate; Cold extrusion forming, drawing film, stainless steel sheet and high hardness material, etc. Such as: for refrigerator compressor back cover drawing mold, quenching hardness 56~58HRC.
1.2379 Steel Flat Bar D2 cold working die steel - Characteristics: In order to improve the service life of flat steel rolled steel of D2 cold working die, the method of adding rare earth is adopted, and the wear resistance and impact toughness of the steel are greatly improved, so as to achieve the purpose of improving the service life of flat steel rolled steel of round die. Because the V and Mo content of D2 steel is higher than that of Cr12MoV steel, it has better comprehensive performance, and the traditional Cr12MoV steel will be gradually replaced. The rolling wheel and cold die made of D2 steel can increase the service life by 5 ~6 times compared with Cr12MoV steel.
