SNCM447 Alloy Steel
SNCM447 alloy steel manufacturers and suppliers, supplied with round rods,square/flat bars,rollers,shafts,blocks and forging pieces.
SNCM447 steel is a common nickel-molybdenum alloy steel accding to JIS standard. It is a high strength steel and has good comprehensive mechanical properties. SNCM447 steel is widely used in the manufacture of the camshaft and connecting rod of engine parts, poor processability, belongs to the typical difficult-to-machine materials.

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.
