SNCM220 Alloy Steel
SNCM220 Alloy steel manufacturers and suppliers, supplied in round rods,square/flat bars,rollers,shafts,blocks and forging pieces.
SNCM220 Steel is a low nickel,chromium-molybdenum alloy steel as per JIS standard. It gives a hard case with a strong core whilst retaining a remarkable degree of toughness. SNCM220 is suitable for parts which require a good toughness and wear resistance.

Hardening is used to meet specific mechanical properties which can make the material fit for use.
Tempering is used to remove the stresses and brittleness caused by quenching, develop the required mechanical properties,and improve dimensional stability and toughness.
Annealing is a process used to soften the material,enhance the machinability and toughness,increase the ductility and improve the homogeneity in material.
Normalizing is used to make material softer , refine the grain size and improve the uniformity of microstructure and properties.
