    Description
    CM15 is a plain carbon steel with a nominal 0.15% carbon content and higher content of S (0.020-0.040%).

    Applications
    Seamless circular steel tubes for mechanical and general engineering purposes. Non-alloy and alloy steel tubes. Steels for case hardening.

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

    Soft Annealing
    Heat to 650-700oC, cool slowly in furnace.

    Carburizing
    Carburizing temperature: 880-980oC.
    Cooling from carburizing temperature: water, oil, air, thermal bath.
    Core hardening temperature: 880-920oC.

    Tempering
    Tempering temperature: 150-180oC.

    Forging
    Hot forming temperature: 1050-850oC.

    Machinability
    Machinability of CM15 steel is fairly good, especially in the cold drawn or cold worked condition. Based upon carbon steel AISI 1112 as a reference that is considered 100% machinable (easily machined) the CM15 steel has a rating of 55%.
