Introduction High Speed Tool Steel (UNS T12004)
High speed tool steel is mainly used in manufacturing high efficient cutting tool.Due to its high red hardness, good abrasion resistance, high strength characteristics, and also used in the manufacture of high performance requirements of the mould, and hot spring roll, high temperature bearing, etc.The use of high speed tool steel after heat treatment the hardness can reach more than HRC63, under the working temperature of 600 ℃ can still maintain a high hardness, but its toughness, wear resistance and heat resistance are good.Annealing state of high speed tool steel main alloy elements tungsten, molybdenum, chromium, vanadium, and some joined the cobalt in high speed tool steel, aluminum and other elements.
