    2.05 0.25 0.30 11.50 - - - - -

    Description
    TMCN1 is Ni-Cr steel with added Mo and V and good thoughness and resistance to temperature changes.

    Applications
    Pilger mandrels up to diameter 140 -200 mm. 

    Physical properties (avarage values) at ambient temperature
    Modulus of elasticity [103 x N/mm2]: 210 
    Density [g/cm3]: 7.85

    Soft Annealing
    Heat to 620-680oC, cool slowly. 

    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 840-870oC followed by oil or air quenching.

    Tempering
    Tempering temperature: 620-670oC.

    Forging
    Hot forming temperature: 1050-850oC. 

    Machinability
    No data.

    Forms manufactured: Please see the  Dimensional Sales Program.
