Material Characteristics

Alloyed structural steel with medium hardenability designed for heavy duty components, characterized by high elasticity and strength properties reaching over 1560 N/mm² at small diameters. When softened, the hardness reaches max. 248 HRB. It is also characterized by its resistance to variable loads and impacts. The material is not suitable for welding and ultimately requires additional preheating.

Applications

Grade 30CrNiMo8 is used for production of heavily loaded parts, shafts and drive axes, steering shafts, crankshafts of engines, screws and elements exposed to temperatures in the power industry. Suitable for automotive and general components which require high demands on strength and toughness and good hardenability. Especially suitable for heavy-duty parts in the aviation, automotive and military industries.
