30crnimo8 is 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
Steel making Process of 30crnimo8 forging round bars
Electric arc furnace or blast furnace and oxygen blast converter shall be used, each with subsequent ladle treatment;
Steel shall be vacuum degassed;
Steel shall be non-radioactive;
Quality class shall beat least MQ in accordance with ISO 6336-5 or DIN 3990-5;
Standard EN 10083 shall be followed.
Chemical composition of 31CrNiMo8 forged parts
Chemical analysis shall be made from a test sample taken just prior to the pouring or during pouring and shall conform to the chemical requirements in the following table:
C 0.26 - 0.34
Si max 0.4
