JIS G4051 Carbon Steel Coils

JIS G4051 carbon steels plates / sheets/ coils/ strips / flat bars are for machine structural use. JIS G4051 steels are manufactured by hot rolling, hot forging and hot extruding. JIS G4051 standard applies to steel products with a uniform cross-section, which are generally supplied for use after further processes of forging, cutting and heat treatment.
