Abstract

Abstract

The present development situation of galvannealed automobile sheet steel at home and abroad was introduced. For galvannealed IF steel, traditional strengthening method and new strengthening technology were introduced, and it was pointed out that galvannealed IF steel is developing to high strength when maintaining good formability. The developing situation of 340 MPa galvannealed bake-hardening steel was introduced in detail. It was pointed out that this steel was developing to good formability, good powdering resistance and good anti-aging. Galvannealed low-carbon equivalent type high-strength steel and dual-phase steel were introduced, too. And they are developing to good formability. Furthermore, the present developing situation of galvannealed TRIP steel were introduced too. It was put forward that galvannealed sheet steel, especially high-strength galvannealed sheet steel, for automobile should be paid attention in China.
