Hot-dip Galvanized Steel Sheets
780 - 1180MPa grade Galvannealed High Strength Steel Sheets for Car Body Structural Parts
Features
- Mass production of GA steel sheets with standard type of strength grade less than
1180MPa for automotive underbody parts requiring corrosion resistance properties. - Superior bendability is suitable for automotive parts produced by forming (bending) or roll-forming.
- Overseas production of GA steel sheets with a standard strength grade less than 1180MPa will be possible in the future.
Examples of Product Characteristics
Mechanical properties of 780MPa - 1180MPa grade GA steel sheets
Possess superior bendability that is suitable for automotive parts produced by forming or roll-forming.

Press forming test results using lubricated 980MPa grade GA steel sheet (center pillar)
Highly-lubricated GA (JAZ) can be applied for high strength GA steel sheets.
Application effectively improves friction coefficient and press-formability compared to conventional GA.

Examples of Applicable Automotive Parts

High strength galvannealed (GA) steel sheets for lightweight underbody parts
Corrosion resistance properties are required, since GA steel sheets are used widely for automotive underbody parts. In 91视频, 780 - 1180MPa grade GA high strength steel sheets with superior bendability have been mass-produced as a standard.
