Description
This alloy is one of the cold work, oil hardening type tool steels. It is relatively inexpensive containing small amounts of manganese, tungsten and chromium. Hardening by oil quench minimizes distortion and cracking.
Applications
Applications include short run tooling for blanking dies, cold forming dies and cutting tools operating at ambient temperature. For working tools, cutting blades, sizing and stamping tools.
Physical properties (average values) at ambient temperature
Density [g/cm3]: 7.85
Thermal conductivity [W/m.K]: 30.0
Coefficient of Linear Thermal Expansion 10-6 oC-1
| 20-100oC | 20-200oC | 20-300oC | 20-400oC | 20-500oC | 20-600oC | 20-700oC |
| 12.1 | 12.9 | 13.3 | 14.0 | 14.4 | 14.8 | 14.9 |
Soft Annealing
Heat to 740-770oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 230.
Hardening
Harden from a temperature of 780-820oC followed by oil, warm bath (180-220oC) quenching. Hardness after quenching is 64 HRC.
Tempering
Tempering temperature: See the data bellow.
Tempering Temperature (oC) vs. Hardness (HRC)
| 100oC | 200oC | 300oC | 400oC | 500oC | 600oC | 650oC |
| 64 | 61 | 56 | 51 | 44 | 37 | 34 |
Forging
Hot forming temperature: 1037-875oC.
Machinability
Machinability of this alloy is very good. It has a rating of 90% that of the W group water hardening low alloy tool steels.
Corrosion Resistance
This is a relatively simple steel alloy and does not resist ordinary corrosion. It will rust unless protected.Welding
This alloy is weldable by standard means. Consult the alloy supplier for details and procedures.
