S275 material properties, Q460 material is a low-alloy high-strength steel. Q stands for the strength of steel. 460 means that plastic deformation occurs only when the strength of the steel reaches 460MPa. That is, when the external force is released, the steel can only maintain the shape of the force and cannot return to its original shape.This strength is greater than that of ordinary steel. Tensile strength is 550-720MPa, elongation: 17%, Q460 material is made by adding Cr, N, V, Ti and other alloying elements on the basis of 16Mn steel.

The company's ESP thin gauge is down to 0.6mm. The thinner the thickness of the S275 material properties, hot rolled steel product, the more difficult it is to roll. The thickness will encounter increased load, severe vibration of the rolling mill, difficult shape control, and fluttering of the head during the downdraft. There are many problems such as difficulty in getting bite, which limit the thinnest size that can be rolled by hot rolling. At present, the thinnest gauge of conventional rolling line is 1.2mm, and the thinnest gauge of CSP production line is about 1.0mm. The successful rolling of 0.6mm hot rolled steel product is a milestone in hot rolled steel strip technology.
