PM23/1.3344 Spray Forming Powder Metallurgy HSS Tool Steel

PM23, also known as ASP2025, is a high-performance spray forming powder metallurgy high-speed steel renowned for its outstanding wear resistance, excellent toughness, and high hot hardness. Manufactured through advanced spray forming technology, PM23 features a highly uniform microstructure with fine, evenly distributed carbides, delivering superior cutting performance, prolonged tool life, and reliable stability in demanding applications.

It is an ideal material choice for wear-resistant cutting tools, stamping dies, shear blades, and other precision tooling operating under high-stress and high-temperature conditions.

Heat Treatment Process for PM23/1.3344 Spray Forming Powder Metallurgy HSS

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 ≤ 255 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 1140-1160°C and hold for a suitable time based on section size.
Quench rapidly in oil, salt bath, or vacuum gas quenching to achieve optimal hardness and a fine, uniform microstructure.

3. Tempering
Temper immediately after quenching to relieve internal stresses and enhance toughness.
The recommended tempering temperature range is 540-600°C .
Double or triple tempering is advised for optimal performance.

After tempering, the hardness typically reaches 64-66 HRC , depending on specific parameters and section size.
