PRODUCT CENTER
W6Mo5Cr4V2Co5 is a tungsten-molybdenum series general cobalt-containing high-speed steel. Compared with W6Mo5Cr4V2, it has improved red hardness and high temperature hardness, improved wear resistance, and has better machinability, but the strength and impact toughness are lower, and it is easy to oxidize and decarburize. W6Mo5Cr4V2Co5 is general Used as gear cutters, milling tools, punches, cutter heads and other tools for cutting hard materials.
W18Cr4V is tungsten high-speed steel, with high hardness, red hardness and high temperature hardness. The wide range of heat treatment difficult to overheat quenching, heat treatment process is not easy oxidation and decarbonization, grinding performance is better. The hardness of the steel is maintained at HRC 63-64 and HRC 62-63 at 500 ° C and 600 ° C, respectively, and has good cutting performance for a large number of general materials to be processed.
GB 20CrNiMo Alloy steel, we can supply the round bar, steel flat bar, plate, hexagonal steel bar and steel square block. GB 20CrNiMo steel Round bar can be sawn to your required lengths as one offs or multiple cut pieces. 20CrNiMo alloy steel Rectangular pieces can be sawn from flat bar or plate to your specific sizes. Ground tool steel bar can be supplied, providing a quality precision finished bar to tight tolerances.
GB/T1591 Q390 contains five different steel grades as Q390A,Q390B,Q390C,Q390D and Q390E.Structural steel Q390D shall be done impacting test at low temperature minus 20 degree centigrade.Normalised heat treatment suggested to be done for low alloy steel plate Q390D in heavy thickness.
CrWMn die steel plate is alloy tool steel, oil quenching low deformation cold working die steel.The steel wearability
