The properties and application of Baosteel＇s inorganic-lubricant-coated galvanized steel sheet are demonstrated. Compared with galvanized steel sheets without the inorganic lubricant coating,the Baosteel inorganic-lubricant-coated galvanized steel sheet has a lower friction coefficient and excellent lubricating ability,more homogeneous tribological and stamping behaviors,lower sensitivity to stamping parameters,excellent spot weldability,good adhesivity,and perfect phosphate compatibility and paintability. These results verify that the Baosteel inorganic-lubricant-coated galvanized steel sheet has excellent press formability and a huge market application potential.展开更多
