按冲压钢板发展的历史和冲压性能水平,可分为三代产品。冲压用钢的主要之一是具有占优势的有利织构,即有利织构系数{111}{110}高。低碳优质沸腾钢代表了第一代产品,它与各向同性的无取向正火钢相比是一个进步,它有较弱的{111}织构,塑性应变比R值为1.0~1.2,冲压成型性较差,沸腾钢中的固溶氮含量较高,具有明显的应变时效性。铝镇静钢是第二代产品,通过对AIN的固溶 According to the history of the development of stamping plate and stamping performance level, can be divided into three generations of products. The main one of stamping steel is to have a predominantly advantageous texture, ie, a favorable texture factor {111} {110}. The low-carbon, high-quality, ebullient steel represents the first generation and represents an improvement over isotropic, non-oriented normalized steels. It has a weaker {111} texture with a plastic strain ratio R of 1.0 to 1.2, Poor press formability, higher nitrogen content in boiling steel, with significant strain aging. Aluminum killed steel is the second generation of products, through the solution of AIN
