Metal Cutting Tools Materials — High speed Steel

The high-speed steel is alloy tool steel containing more alloying elements such as W, Mo, Cr, V, and better overall performance, the widest range of applications of a cutting tool materials. After heat treatment hardness of 62-66HRC, flexural strength of about 3.3GPa, heat resistance to 600 ℃, addition, has the advantages of heat deformation small, can be forged, and easy to grind the sharp edge. The use of high-speed steel is a large proportion, especially for the manufacture of a complex structure of the forming tool. Such as various types of hole machining tools, milling cutters, broaches, thread cutting tools, gear cutting tools, etc.
