Product Description
tool steel
High Speed Steel Round Bar and Plate
High speed tool steel comprises a set of tool steel alloys named for their capacity to cut materials faster than traditional high-carbon steels previously used in cutting tools.
*High alloy content, primarily tungsten or molybdenum, with lesser amounts of chromium, vanadium and cobalt;
*High carbon content-a minimum of 0.65% by weight, but commonly anywhere from 0.8% to 1.5% carbon content;
*Rockwell hardness of at least 64 HRC at room temperature;
*A heat treatment process that produces a high quantity of complex metallic carbides-chiefly tungsten, molybdenum and vanadium carbides-suspended in a steel substrate, which results in hardness and wear resistance.
