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. 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.

Application of 30CrNiMo8 Alloy Steek

30CrNiMo8 steel is used for automotive and general components which require high demands on strength and toughness and good hardenability. It is especially suitable for heavy-duty parts in the aviation, automotive and military industries.
Applications of 30CrNiMo8: For permanently stressed components with large cross sections for automotive and mechanical engineering. For economic performance under severe dynamic stress, parts must be designed for optimum strength or toughness.
