12th International Conference on Zinc & Zinc Alloy Coated Steel Sheet - GALVATECH 2021

The Zinc Alloy Coated Steel Sheets are mainly used for the plates of Automotive. Especially, the interstitial free steel is used to the outer panel and it is manufactured by press forming in the process of automotive manufacturing. The materials are needed of high formability because the press formed parts have some complicated shape, therefore high elongation of mechanical properties are important. The mechanical properties are mainly ruled in the component and a CGL heat pattern can make fine adjustment. The mechanical properties can only be measured by off line tensile testing. However it is difficult to change the properties after CGL manufacturing if the test results don’t meet the criteria. Here we show the prediction model of the mechanical properties based on the records of CGL heat pattern experience. By using this model, you can predict the mechanical properties and can adjust CGL heat pattern optimization at once.
