SPHC/SPHD/SPHE steel sheet
SPHC has added special elements (P, Cu, C, etc.) and has good corrosion resistance and atmospheric corrosion resistance. SPHD has a thickness of 1.2 - 8mm and a width of less than 600mm, which is called narrow strip steel, and those over 600mm are wide strip steel. Its carbon content is slightly higher than that of cold-rolled steel plates. When the components are not much different, its density is the same as that of cold-rolled steel plates. SPHE is made by pressing low-carbon steel and ordinary alloy steel at high temperature.
