GB/T700 Q275 carbon steel and low alloy steel coil equivalent material is S275JR steel plate. S275JR steel coil is a general purpose carbon structural steel. This steel is similar to the steels listed in China GB/T700 and GB/T1591. It is also a carbon structural steel and low alloy structural steel used in engineering steel and structural steel, which is usually not heat treated. GB/T1591 steel coil is a Chinese standardized low alloy medium tensile strength steel coil produced by hot rolling process. GB/T1591 steel coil has a variety of manufacturing purposes.
