Features and Scope
30crni3 alloy structural steel, the steel has good hardenability, high strength and toughness by quenching with a good comprehensive mechanical properties. Good machinability, but the cold deformation plasticity is low, poor welding. For the production of high impact load by the torsion and hardenability and requirements automobile orientation axis, front axle, drive shaft, crankshaft, gears, worm, also used as a shaft, connecting rod, keys, bolts, nuts and so on. Generally used in the quenched and tempered.
