High Speed Steels are highly alloyed steels designed to cut other materials efficiently at high speeds while withstanding extreme heat generated at the tools cutting edge. These steels are heat treated and used at high hardnesses (62 HRc and above), maintaining the high hardness at elevated temperatures while having enough impact toughness to handle interrupted cut tooling applications.
M2 is the most popular grade of high speed steel worldwide and commonly used in a wide variety of cutting tools and metal forming applications. Rounds: .109" dia through 10.125" dia Flats: .055" thick through 3" thick saw cut widths up to 36"
PSB M2 is a premium spray formed M2 High Speed Steel. It is ideal for many high speed applications providing improved toughness and higher wear resistance than conventional M2. The spray forming process imparts a more homogeneous structure with improved carbide distribution and a preferred spherical carbide shape.
