Introduction to High Speed Steel

High speed steel (HSS) is a tool steel with high hardness, high wear resistance, and high heat resistance, also known as high-speed tool steel or front steel, commonly known as white steel. High speed steel was invented in 1898 by F. W. Taylor and M. White of the United States.

High speed steel has good processing properties and a good combination of strength and toughness, so it is mainly used to manufacture complex thin blades and impact resistant metal cutting tools, as well as high-temperature bearings and cold extrusion molds. In addition to high-speed steel produced by smelting, powder metallurgy high-speed steel emerged after the 1960s, with the advantage of avoiding carbide segregation caused by smelting, resulting in reduced mechanical properties and heat treatment deformation
