High speed steel bar is mainly used for cutting tool applications, such as twist drills, taps, milling cutters, reamers, saw blades, broaches, roll-to-inserts, gear cutters and other gear cutters. In addition to cutting tools with red hardness requirements, the material can also be used as cold work tool steels, such as die cutting, forming and embossing.

Heat Treatment
Annealing:
Annealing temperature is 860-880℃, keep this temperature by 2-4 hours, then cooling to 600℃ in the speed of 20-30℃/h.
For cold drawn process, the material will be processed with stress relieving annealing process under temperature of 600-700℃, and keep this temperature by 2 hours.
Quenching:
Pre-heating in two steps:
Heating temperature under 400-500℃ and 850-900℃.
Austenitizing temperature with 1185-1225℃
Heating coefficient 10-15 sec/mm, quenching under 580-620℃, then cooling to room temperature.
Tempering:
Tempering temperature under 540-560℃ , tempering 3 times, each time 1 hour, then cooling to room temperature.
