Welcome to Tianjin TISCO，Steel expert by your side.
DIN 30CrNiMo8 steel is an alloy steel formulated for primary forming into wrought products.
DIN 30CrNiMo8 alloy steel Description
DIN 30CrNiMo8 material is one 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 it is softened, the hardness reaches max. 248 HRB.
It is also characterized by its resistance to variable loads and impacts.
However, it is not good for welding and it ultimately requires additional preheating.
Heat Treatment of DIN 30CrNiMo8 alloy steel
Soft Annealing
Heat to 650-700oC, cool slowly. This will produce a maximum Brinell hardness of 248.
Normalizing
Temperature: 850-880oC.
Hardening
Harden from a temperature of 830-880oC followed by oil quenching.
Tempering
Tempering temperature: 540-680oC.
