ASP® 2012 Powder Metallurgy High-Speed Steel

Material available in round and flat sections

ASP® 2012 is the best in class for high toughness up to 62-63 HRC in plastic, cold, warm, and hot applications.

Applications

Cold work tools: powder compacting tools, cold extrusion tools, cold-heading dies, fine blanking tools
Plastic injection: mould for fibers reinforced plastics, broaches and injector pins
Machine components and rolls
Warm and hot-work applications: extrusion dies, forging dies and punches, press hardening tools

Heat Treatment

Soft annealing in a protective atmosphere at 850-900°C for 3 hours, followed by slow cooling at 10°C/h 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 in a protective atmosphere with preheating in 2 steps at 450-500°C and 850-900°C and austenitising at a temperature suitable for chosen working hardness. Cooling down to 40-50°C.
The temperature tempering range from 520 to 560°C, depending on the hardening temperature, the application and the targeted hardness (55 to 63 HRC). Cooling to room temperature 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 and tempering 3 x 1 hour
