Research on Process Optimization of 560MPa Grade Sheet for Automobile Crossbeam

Abstract:

In this paper, according to the problem of elongation unqualified in 560MPa grade sheet for automobile crossbeam in Pangang, through the microstructure detection、fracture observation and other methods to analysis the reason of elongation unqualified and propose process optimization measures. Used the measures, the elongation unqualified situation has obvious improvement in P560L, greatly improved qualified rate. The performance fluctuating range is small behind process optimization and have excellent forming properties and low temperature impact toughness. The users applied show that: products have excellent stamping performance, small rebound after stamping and stable quality. The various performances fully meet the used requirements of punch vertical frame in automobile.
