High-speed steel saw blades have high hardness, high wear resistance and high heat resistance of tool steel, also known as high-speed tool steel or front steel. High-speed steel has good process performance and good strength and toughness.

It is mainly used to manufacture complex thin-blade and impact-resistant metal cutting tools, as well as high-temperature bearings and cold extrusion dies. In addition to the high-speed steel produced by the smelting method, powder metallurgy high-speed steel appeared after the 1960s, which has the advantage of avoiding the segregation of carbides caused by the production of the smelting method and causing the mechanical properties to be lowered and the heat treatment deformation.Contor flying saw cutoff machine adopts HSS saw blade and TCT saw blade for cutting metal tube and pipes inline in ERW tube mill.
