SCr420 Alloy structural steel
SCr420 Alloy structural steel

SCr420 is a Alloy structural steel,Alloy structural steel, used as a mechanical part and a variety of engineering components and contains one or more of a certain amount of alloying elements of steel.

Standard: JIS G4053-2003

Its strength and high hardenability, Quenched and tempered, can obtain the comprehensive mechanical properties and low temperature impact toughness is good, no temper brittleness, so it should be two times the quenching to improve core toughness, unfavorable cooling quenching, cold plastic deformation can be high, cold drawing, high temperature normalizing and tempering, good processability, good weldability. The welding shall be preheated to a temperature of 100-150 DEG C, the general carbon steel as the penetration.
