BR400/590TR,BR400/590TR steel
TRIP Steel is the abbreviation of Transformation Induced Plastics steel. As one of AHSS, the microstructure of TRIP steel is made up of ferrite, bainite and retained austenite. It has solved the contradiction between strength and ductility. It has high strength while it has good plasticity, too. This specific property can meet the formation requirements of automobile parts with complex shape which the good ducticity is needed.
