china 201 stainless steel coil supplier 201 steel coil Manufacturerssaid ASME and ASTM said there are several : SA240-304, and SA240TP304, and A240-304, and A240TP304, in fact, middle - and TP's idea is the same. We 304L in front of the material, where l is the suffix, with low carbon content ; can often be seen with h, said higher carbon content, mainly used in high temperature occasions ; n are also common, adding elements n, enhances the intensity. Sometimes, we can also be seen in the back : 2B,No. 1 suffix, is the material of the surface state of these suffixes ; 2B after hot rolling and cold rolling, good on the surface, plate reaches mirror finish requirements ; wtri said after hot rolling and cold rolling, surface of steel sheet ; No. 1 indicates that the hot surface.
