Product Detail

Designation by Standards

Chemical Composition (in weight %)

Description
 M7 is one of the High Speed Tool Steels in the molybdenum alloy family, with tungsten, chromium and vanadium for strengthening. It has good hardenability and is very wear resistant. Very high resistance to softening at elevated temperatures and good toughness. Deep hardening response.

Applications
 M7 is widely used for cutting tools in machining operations. Sendzimir rolls, segment and circular cutters, profile cutting tools, thread cutting drills and cold forming tools.

Physical properties (avarage values) at ambient temperature
 Modulus of elasticity [10³ x N/mm²]: 217
 Density [g/cm³]: 8.30
 Thermal conductivity [W/m.K]: 19.0
 Electric resistivity [Ohm mm²/m]: 0.65
 Specific heat capacity[J/g.K]: 0.46

Coefficient of Linear Thermal Expansion 10^-6oC^-1

Soft Annealing
 Heat to 820-880^oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 230-280.

Hardening
 Heat up to 450-600^oC, preheat to 850^oC and then to 1050^oC. Harden from a temperature of 1180-1220^oC followed by oil, air quenching or warm bath at 550^oC. Hardness after quenching is 64-66 HRC.

Tempering
 Tempering temperature: 3 x 1 hour at 540-560^oC. Hardness after tempering is min 64 HRC.

Forging
 Hot forming temperature: 1100-900^oC.

Cold Working: In the annealed condition M7 may be cold worked by conventional methods.

Machinability
 Machinability is medium, rating about 60% that of the W group water hardening low alloy tool steels at 100% for comparison.

Corrosion Resistance
 Although this alloy contains chromium and molybdenum it is still a steel and thus will corrode. It should be protected from rusting.

Welding
 This is a complex alloy but is weldable. Consult the supplier for procedures and details.

Forms manufactured: Please see the Dimensional Sales Program.
