|0.35||max. 0.40||0.65||max. 0.40||max. 0.10||max.0.40||-||-||(Cr+Mo+Ni) = max. 0.63|
Non alloy special sructural steels: Structural steels with average C < 0,50%.
Steels for quenching and tempering, automobile and motor construction parts.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.86
Heat to 650-700oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 183.
Normalizing temperature: 860-900oC.
Harden from a temperature of 840-880oC, 840-880oC followed by water or oil quenching.
Tempering from the quenched condition may be done at 550-660oC depending upon the strength desired.
Hot forming temperature: 1100-850oC.
Machinability is good, rated at 60% that of the AISI 1112 alloy used as a 100% machining rated steel.
This is a steel alloy and will rust if not protected. it is not corrosion resistant.
CM35 steel is weldable by all of the welding methods. However with its higher carbon content it is important to use both pre-heat at 150 to 260oC and post-heat at 590 to 650oC practice per an approved welding procedure.
In the annealed state the CM35 alloy is readily cold worked by conventional methods.
