Low carbon steel cold rolled strip (YB/T5059-1993)

Low-Carbon Cold Rolled Steel Strip (YB/T5059-1993) Introduction Low-carbon cold rolled steel strip is a type of steel that has been processed in a cold rolling mill. It has been subjected to significant cold rolling which has reduced the thickness of the steel. This process also improves the strength and surface hardness of the steel and makes it more suitable for use in a range of applications. The YB/T5059-1993 standard specifies the chemical and mechanical properties of low-carbon cold rolled steel strip. This standard also sets out product specification requirements including width and thickness, as well as other physical properties such as surface finish and coating (if applied). Chemical Composition The typical chemical composition of low-carbon cold rolled steel strip is outlined in Table 1. Table 1: Typical chemical composition of low-carbon cold rolled steel strip (YB/T5059-1993). Carbon (C) 0.06-0.12% Manganese (Mn) 0.60-1.0% Silicon (Si) 0.25-0.50% Sulfur (S) values lower than 0.05% Phosphorus (P) values lower than 0.05% Mechanical Properties The mechanical properties of low-carbon cold rolled steel strip are outlined in Table 2.
