摘　　要：热轧酸洗深冲钢板采用超低碳和钛微合金化等工艺 ,获得渗碳体含量极少的等轴铁素体组织 ,伸长率和杯突值高 ,实物质量达到冷轧深冲钢 St1 4的水平 ,是武钢开发的“以热代冷”即以热轧钢板代替部分冷轧钢板的新一代系列深冲钢板之一。Hot rolled and pickled deep drawing steel strip has a microstructure of proper grain size,equiaxed ferrite and little amount of cementite by deep decarburization and Ti micro alloying The steel strip has the same quality in terms of elongation and IE value as cold rolled deep drawing St14 strip and can be used to manufacture the parts of complex form such as refrigerator's components instead of cold rolled steel sheet
