30CrNiMo8 1.6580 forged round bar alloy steel 30CrNiMo8 steel Manufacturer

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.
