Performance Purpose:

34CrNiMo6 is similar to 42CrMo in performance and has high strength and good toughness. It is used to manufacture important structural [TJC STEEL]parts for high load work, such as wind turbine spindles, high-speed train axles, torsion shafts of armored vehicles, crankshafts and connecting rods for heavy diesel engines, and gears for other heavy duty parts.
