Alloyed with balanced levels of carbon, vanadium, molybdenum, and cobalt, PM30 / 1.3294 offers an excellent combination of wear resistance and toughness.
Commonly known as ASP2030, this spray forming powder metallurgy high-speed steel provides superior edge retention and thermal stability under demanding cutting conditions. The advanced spray forming process ensures a uniform, fine microstructure with evenly distributed carbides, resulting in high dimensional stability and extended tool life.
PM30 is especially suitable for high-performance cutting tools, broaches, end mills, reamers, and punches that require a balance of toughness and wear resistance under both thermal and mechanical load.

1. Annealing
Slowly heat the steel to 850-900°C and hold for 2-4 hours. Then allow the furnace to cool below 600°C, followed by air cooling.
This process results in an annealed hardness of ≤ 280 HB, ensuring good machinability before hardening.
2. Hardening (Quenching)
Preheat in stages:
First to 450-500°C
Then to 850-900°C
Finally, heat to the austenitizing temperature of 1180-1200°C, with appropriate holding time based on cross-sectional thickness.
Rapid quenching in oil, salt bath, or vacuum gas is recommended to achieve a fine, uniform microstructure and optimal hardness.
3. Tempering
Tempering should be done immediately after quenching to relieve internal stresses and enhance toughness and dimensional stability.
The recommended tempering temperature range is 540-600°C. For best performance, double or triple tempering is recommended.
After tempering, the hardness typically reaches 65-68 HRC, depending on section size and process control.
