210P1表面疑似红锈问题探讨

The 210P1 Strip Surface Suspected Red Rust Problem Discussed

210P1属于典型的含磷高强IF钢,由于具有高强度和良好的成形性能,广泛应用在汽车行业,特别是翼子板、发动机盖外板、车顶横梁外板等,作为这些覆盖件,除了冲压性能,表面质量也是客户关注的重点指标,近期某钢厂生产的210P1表面存在疑似红锈的缺陷,通过分析,界定了缺陷,为生产判定提供了依据,并提出了问题改进方向。

210P1 belongs to typical phosphorus high strength IF steel, because of the high strength and good forming per- formance, widely used in the automotive industry, especially the fender, engine cover plate, roof beam plate, etc., as these covering parts, in addition to the stamping properties, surface quality and customer focus, the recent 210P 1 surface of a steel mill production suspected the defects of hot rolled red rust, through the sample analysis, def＇mes defects, and pro- vide the basis for production decision. And put forward the improvement direction of the problem.
