Steel Coil Material Difference - Q235 and SPCC

The difference:usually SPCC is cold-rolled process, the surface is smooth and beautiful, and the elongation performance is good; Q235 is generally hot-rolled and the surface is relatively rough. Uses:SPCC is widely used in many fields, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans, etc. Q235 is primarily used for a variety of Cold Rolled Steel AK SteelCold Rolled Steels are available in thicknesses from 0.015 0.135 in. (0.381 3.429 mm), and widths to 80 in. (2032 mm), depending on dimensions and product quality. The standard coil inner diameter is 24 in. (609 mm). Thickness, width, and flatness tolerances are covered in ASTM A568. 3 COLD ROLLED
