After several years of development, Sichuan Liaofu Special Steel Industry Co., Ltd mainly produce die steel, high alloy steel smelting, refining, forging, machining, heat treatment of high-quality goods, and formed complete production management system, our company is a private enterprise, the hometown of abrasive tool steel production in China - hubei, the transportation is convenient, the factory has international advanced production equipment, product quality testing equipment. Company's major equipment: there are 3 tons, 4 tons of electric furnace smelting equipment, 0.5 tons, 1 tons, 3 tons, 5 tons of electroslag furnace, including 3 tons, 5 tons of electroslag furnace and has the function of large steel ingot smelting, steel processing equipment are: active, auxiliary equipment of producer gas generator, continuous heating furnace, annealing furnace, the electric car type annealing furnace.All-hydraulic electric grinding wheel peeling machine, electric band saw, gantry sawing machine, etc.The detection equipment has the chemical analysis, the physical examination, the mechanical performance detection advanced instrument.
we have DC53 / Cr8Mo2SiV mould steel
DC53 is to improved new type of cold work die steel SKD11, its technical specifications in the Japanese industrial standard (JIS) G4404.It overcomes the insufficient SKD11 high temperature tempering hardness and toughness of weakness, will fully replace in the field of general and precision mould SKD11. DC53 heat treatment hardness is higher than SKD11, high temperature (520-530 ℃) can reach 62-62 HRC after tempering high hardness, more than SKD11 DC53 in terms of strength and abrasion resistance. Toughness is 2 times of SKD11, DC53 toughness is more prominent in the cold work die steel, made of DC53 tools rarely appear crack and craze, greatly improving the service life. After wire-cutting processing of the smaller residual stress by high temperature tempering to reduce the residual stress, crack and deformation after wire-cutting processing, be suppressed. Cutting and grinding than SKD11, cutting and grinding of DC53 better than SKD11, use DC53 can increase the tool life and reduce the processing procedure
