High Performance F68 Spray Forming Powder Metallurgy HSS Tool Steel 

High Performance F68 Spray Forming Powder Metallurgy HSS Tool Steel is a premium high-speed steel manufactured by advanced spray forming technology. It combines the advantages of powder metallurgy and spray forming, offering superior wear resistance, excellent red hardness, and outstanding toughness.

F68 Powder Metallurgy HSS is ideal for producing wear-resisting press tools, guide plates, precision punch pins, stamping dies, cutting tools, and industrial blades. Its fine and uniform microstructure ensures enhanced tool life, dimensional stability, and resistance to cracking under heavy loads.

Heat Treatment Process for F68 Spray Forming Powder Metallurgy HSS

1. Annealing

• Heat the material slowly to 850-900°C , hold for 2-4 hours , then furnace cool to below 600°C , followed by air cooling.

• This process achieves an annealed hardness of ≤ 255 HB , ensuring good machinability before final heat treatment.

2. Hardening (Quenching)

• Preheat in two steps:

  • First to 450-500°C

  • Then to 850-900°C

• Finally, heat to the austenitizing temperature of 1020-1120°C , hold for an appropriate time (depending on section size), then quench in oil, salt bath, or gas (vacuum) for best results.

3. Tempering

• Temper immediately after quenching to reduce internal stress and enhance toughness.

• Recommended tempering temperature: 520-550°C

• Double or triple tempering is advised for optimal performance.

• After tempering, the hardness can reach 57-64 HRC , depending on exact conditions.
