SCM435
It has high static strength, impact toughness and high fatigue limit, higher hardenability than 40Cr, high creep strength and lasting strength at high temperature, long-term working temperature up to 500℃; Medium plasticity and poor weldability during cold deformation.Used as important structural components working under high loads, such as transmission parts of vehicles and engines; Turbine generator rotor, main shaft, heavy load transmission shaft, large section parts.
