STEEL DESIGNATION

NORMS INTERNATIONAL COMPARISON

39NiCrMo3 Good hardening penetration steel, suitable for the construction of components that should be resistent to twisting and bending. It is characterized by the lack of fragility in
tempering.

18NiCrMo5 For medium and big depth components that should be carbonized. This type of steel combines a great hardness of the surface with a very strong centre and it buckles very littl
during the hardening. Case-hardening at 870°/900°. It is recommended to practise the double hardening: the first of 860° toughness in oil, the second of 800°/830°C hardness in oil.

11SMnPb30/37 inproved sheddering steel, for manufacturing on machines tool with shaving removal. It contains some alloy elements, among them the sulphur (S) and the lead (Pb) that
simplify the shaving cutting up and the lubrication of the tool cutting. It is not designed for a heat treatment.

100Cr6 good non-deformable steel and wear resistance. It is very suitable for the manufacturing of rings, bearings, balls, rollers, etc…
