Delivery Condition
EAF+LF+VD+(ESR), Hot rolled or Forged, Annealed, EFS, Hardness≤235HB, Un-machined or
Machined surface (Peeled, Turned, Milled, Grinded), UT 100% Passed
Characteristics
Hot work tool steel featuring a fine combination of heat checking resistance, hot strength and impact strength; admits water cooling.
Applications
1. Highly stressed hot work tools, mainly for the processing of heavy alloys, such as mandrels, dies
and containers for metal tube and rod extrusion; hot extrusion tools;
2. Tools for the manufacture of hollows, screws, rivets, nuts and bolts.
3. Die casting tools, forming dies, die inserts, hot shear blades.
Heat Treatment
Annealing
750 to 800°C (1382 to 1472°F)
Slow controlled cooling in furnace at a rate of 10 to 20°C/hr (50 to 68°F/hr) down to approx. 600°C (1112°F), further cooling in air. Hardness after annealing: max. 235 HB.
Stress relieving
600 to 650°C (1112 to 1202°F)
Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or in complex shapes. After through heating, hold in neutral atmosphere for 1 - 2 hours.
Hardening
1010 to 1050°C (1850 to 1922°F)
Oil, salt bath (500 - 550°C / 932-1022°F), air
Holding time after temperature equalization: 15 to 30 minutes.
Obtainable hardness: 52 - 56 HRC
Tempering
Slow heating to tempering temperature immediately after hardening / time in furnace 1 hour for each 20 mm of work piece thickness, but at least 2 hours / cooling in air. It is recommended to temper at least twice. A third tempering cycle for the purpose of stress relieving may be advantageous.
1st tempering approx. 30°C (86°F) above maximum secondary hardness.
2nd tempering to desired working hardness. The tempering chart shows average tempered hardness values.
3rd for stress relieving at a temperature 30 - 50°C (86 to 122°F) be low highest tempering temperature.
