General high speed steels are used widely, 75%t of total amount of high speed steel. Mass fraction of carbon is 0.7%~0.9%. We can classify high speed steel into tungsten serial and molybdenum serial according to different content of tungsten and molybdenu
High speed steel with high performance refers to the steel increasing V (＞2.50%) or Co (≥ 4.5%) or Al(0.80~1.20%) and carbon at the same time, based on general high speed steel. Its hardness can reach 65~70HRC at room temperature. Wear Resistance and heat
Low alloyed high speed steel refers to the high speed steel with tungsten (＝W＋1.8Mo)content of 6.50-11.75%. Heat resistance and wear resistance of low alloyed high speed steel reduces, which can be applied into the material with low cutting speed requirem
Because of inert gas atomization and rapid solidification of droplet deposition ,the spray formed HSS has low oxygen content , overall high density and fine microstrcture.
Powder metallurgy HOP HSS is featured by its fine and evenly distributed carbides in the matrix, and therefore has the special preoperties of high toughness in all directions. As compared to HSS produced through other metallurgical process, the PM HSS can
HEYE brand cold word die steels are manufactured via ESR,unique forging and heat treatment process, with high strengh and wearresistance, cold and hot applications,high toughness and high isotropy performance.
HEYE brand hot work steels are maufactrued via ESR,unique forging and heat treatment process,with high performance of high strenth and toughness, high hot strengh, both hot and cold application, and high toughness and toughness.
HY608A is the cutting tool steel specially developed for the production of machine blade, cutting cloth cutter, blades, jig saw, drill, tap etc.
