Brand Name: BOZHONG
Key Specifications/Special Features:
Hot rolled alloy steel round bars & rodsRevne no.: 873Materials no.: 1.3255DIN: S18-1-2-5EN: HS18-1-1-5AISI: T4Chemical composition (in weight %)C: 0.79%Si: 0.45% max.
Mn: 0.40% max.

Others: 4.75%
Description
This alloy is a high speed, tungsten type tool steel. It is a deep hardening alloy capable of Rockwell C 64 hardness.
Applications
Generally used as cutting tools, broaches and cold extrusion punches, turning, planing and milling cutters for roughing work.
Physical properties (average values) at ambient temperature
Modulus of elasticity [103x N/mm2]: 217
Density [g/cm3]: 8.70
Thermal conductivity [W/m.K]: 19.0
Electric resistivity [Ohm mm2/m]: 0.65
Specific heat capacity [J/g.K]: 0.46
Soft annealing
Heat to 820-850oC, cool slowly in furnace to 550oC then air. This will produce a maximum Brinell hardness of 265.
Stress relieving
Stress relieving to remove machining stresses should be carried out by heating to 600-650oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening
Harden from a temperature of 1260-1290oC followed by oil, air quenching or warm bath at 550oC. Hardness after quenching is 63-66 HRC.
Tempering
Tempering temperature: 2x 560-580oC. Hardness after tempering is 64-65 HRC.
Forging
Hot forming temperature: 1150-900oC.
Cold working
In the annealed condition the alloy may be cold worked by conventional methods.
Machinability
Machinability of T4 is only fair. It ranks as 55% that of the W group water hardening simple tool steels.
Corrosion resistance
Although this alloy contains appreciable amount of tungsten it is still not a corrosion resistant alloy. it will rust unless adequately protected.
Welding
The alloy may be welded but has a high tungsten content. Consult the alloy supplier for information relative to welding methods.
