低合金09MnRE冷轧钢板是25/38公斤级的薄板,主要用于汽车制造冷冲压成型的结构件。鞍钢采用包内压入法加入稀土硅铁合金冶炼生产09MnRE钢,钢质洁净,硫含量≤0.010％,非金属夹杂物为RE_2O_2S为主的小颗粒状。冷轧钢板的性能稳定,塑性好(δ_5≥40％),宽冷弯性能好(弯180°d=0 100％完好),所以冷冲压性能较优越,冲压拉延件、汽车发动机挡板和小油底壳等十五万余件达100％完好。低合金09MnRE冷轧钢板是汽车制造的优良钢材,年获经济效益五十多万元。
Low-alloy 09MnRE cold-rolled steel sheet is 25/38 kg-class sheet, mainly used in automotive manufacturing cold stamping of structural parts. In Ansteel, the 09MnRE steel is produced by the process of pressing into the rare-earth ferrosilicon alloy with the pressure inside the bag, the steel content is less than or equal to 0.010%, and the non-metallic inclusions are small particles mainly composed of RE 2 O 2 S. Cold-rolled steel has the advantages of stable performance, good plasticity (δ_5≥40%), wide cold bending performance (180 ° d = 0 100% intact), so the cold stamping performance is superior, the stamping and drawing parts, automobile engine baffle and Small oil pan more than 150,000 pieces of 100% intact. Low-alloy 09MnRE cold-rolled steel plate is an excellent steel for automobile manufacturing, the annual economic benefits of more than 500,000 yuan.
