SCM435 Alloy Steel



Material Name


Material Name: SCM435
Execution standard: JIS G4053-2008

Characteristics and scope of application


Have a high static strength, impact toughness and high fatigue limit, quenching of was higher than that of the 40Cr and high temperature with high creep strength and rupture strength, long-term working temperature of up to 500 DEG C; when the cold deformation plastic medium and poor weldability. Used as an important structure of the work pieces under high load, such as the transmission of a vehicle and engine parts; turbo generator rotor, spindle, heavy load transmission shaft, large section parts.
