THE MECHANICAL PROPERTIES OF SCM430 ROUND BAR
SCM430 is a chromium-molybdenum alloy steel as per Japan Standard. JIS SCM430 steel contains a lower carbon content but provides better weldability comparing with SCM440 Steel. SCM430 round bar is frequently applied to the gas & oil area.Typical applications include components such as valve bodies,pumps and hydraulic cylinder fittings like cylinder rod .
