M35+V Spray Forming Powder Metallurgy HSS Tool Steel is an upgraded high-speed steel material based on traditional M35, with increased vanadium (V) content to significantly enhance wear resistance and cutting edge stability. Manufactured through advanced spray forming powder metallurgy technology, this steel offers a fine, uniform microstructure with superior toughness and hardness balance. It delivers excellent performance in demanding cutting applications, especially for slow cutting hobs and precision cutting tools, offering a more cost-effective solution without compromising tool life or cutting efficiency.

1. Annealing
Slowly heat the steel to 850-900°C and hold for 2-4 hours. Then, allow the furnace to cool to below 600°C, followed by air cooling.
This process achieves 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 1190-1210°C, holding for a suitable time based on the section size.
Rapid quenching in oil, salt bath, or vacuum gas ensures optimal hardness and a fine, uniform microstructure.
3. Tempering
Temper immediately after quenching to relieve internal stresses and enhance toughness.
Recommended tempering temperature: 540-600°C
For optimal performance, double or triple tempering is suggested.
After tempering, the hardness typically reaches 65-67 HRC, depending on section size and specific process parameters.
