Consumption process of galvanized square tube: the heating is not stopped during consumption, so there are no defects such as pockmarks and iron oxide scale that often appear in hot rolling, and the surface quality is good and the brightness is high. Skin and other defects, good surface quality and high brightness. Moreover, the dimension precision of cold rolled products is high and the dimension precision of cold rolled products is high. The performance and structure of products can meet some special application demands, such as electromagnetic performance, deep drawing performance, etc. Electromagnetic performance, deep drawing performance, etc. Tool steel has good wear resistance, that is, ability to resist wear. Good wear resistance, that is, ability to resist wear. The shape and size of the tool can remain unchanged even under the condition of bearing considerable pressure and friction.
