Structure of coating
Examples of Product Properties
Examples of press formability evaluation results
Due to its excellent lubricity, the formable range expands and contributes to stabilizing the pressing process.
Example of application to GI
Compared with conventional GI, the friction coefficient is greatly reduced
It also exhibits excellent lubicity at the same or a higher level compared with EG Pre-phos.
Examples of Applicable Automotive Parts
Fender
Side panel
All kinds of outer and inner parts of the automobile body (ex. side panel)
GA/GI coated steel sheets with excellent press-formability by surface lublication
High-lubricity GA / GI steel sheets enable severe press forming of outer and inner parts of the automobile body and contribute to lowering the grade of base steel sheets.
