ASP® 2080 Powder Metallurgy High-Speed Steel

Material available in round and flat sections

ASP 2080 is a high alloyed grade developed for dry cutting applications where the need of wear resistance and high hardness in combination with relatively high toughness is important.

4-Point Bend Strength

Tempering 2 x 1 hour at 560°C

Dimension of test piece Ø 4.7 mm

Rmb = Ultimate bend strength in kN/mm²

Reb = Bend yield strength in kN/mm²

Tot. work = Total work in Nm

Heat Treatment

Soft annealing in a protective atmosphere at 850-900°C for 3 hours, followed by slow cooling 10°C per hour down to 700°C, then air cooling.
Stress-relieving at 600°C to 700°C for approximately 2 hours, slow cooling down to 500°C
Hardening according to curve. Cooling down to 40-50°C
Tempering at 560°C three times for at least 1 hour each time. Cooling to room temperature (25°C) between tempering

Surface Treatment

The steel grade is a perfect substrate material for PVD coating. If nitriding is requested, a small diffusion zone is recommended but avoid compound and oxidized layers.

Guidelines For Hardening

Tempering temperature in °C

Hardness after hardening, quenching, cryogenic treatment and tempering
