Description
Tungsten-chromium hot work steel suitable for water cooling.

Applications
Water cooled dummy blocks for the extrusion of copper and copper alloys, hand casting chills for copper alloys. 

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [10³ x N/mm²]: 210 
Density [g/cm³]: 7.80

Soft Annealing
Heat to 820-840^oC, cool slowly in furnace. Holding time 4-6 hours. This will produce a maximum Brinell hardness of 230.

Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to 650^oC, holding for one hour at heat, followed by slow cooling. Time is 1-2 hours. This operation is performed to reduce distortion during heat treatment.

Hardening
Harden from a temperature of 960-1050^oC followed by water or oil quenching. Hardness after quenching is appr. 52 HRC (water quenching), 47 HRC (oil quenching).

Tempering
Tempering temperature: 560-700^oC.

Nitriding
Possible. Preheating before use: 200-300 ^oC, absolutely necessary.

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.
