Description
This alloy is on of the cold work, oil hardening type steel/" target="_blank" class="keylink">tool steels.
Applications
Planing machine blades, tap drills, machine blades for cutting paper, paperboard and tobacco.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: Approx. 210
Density [g/cm3]: 7.80
Coefficient of Linear Thermal Expansion 10-6 oC-1
20-100oC | 20-200oC | 20-300oC | 20-400oC | 20-500oC |
11.0 | 12.5 | 13.3 | 13.8 | 14.1 |
Soft Annealing
Heat to 720-750oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 230.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening
Harden from a temperature of 780-820oC, 800-860oC followed by water or oil quenching. Hardness after quenching is min. 64-65 HRC.
Tempering
Tempering temperature: 150-300oC.
Tempering Temperature (oC) vs. Hardness (HRC)
100oC | 200oC | 300oC | 400oC | 500oC |

Tempering Diagram
Forging
Hot forming temperature: 1050-850oC.
Machinability
No data.
Corrosion Resistance
Corrosion resistance of this alloy is better than that of plain carbon steels. However it will rust unless given protective treatment.
