日本ＮＫＫ公司克服以往冲压成型工艺中存在的缺陷 ,成功开发出新型汽车用无取向高碳冷轧薄带钢———Ｓ35Ｃ无取向薄带钢。这种新型钢种通过控制热轧过程中钢的珠光体组织并优化冷轧和退火工艺加以生产。特别是在生产过程中细化碳化组织并取消晶粒取向 ,同时改进其成形性能和 Japan NKK company to overcome the shortcomings of the past stamping process, the successful development of a new type of automotive non-oriented high-carbon cold-rolled strip - S35C non-oriented thin strip. This new steel is produced by controlling the pearlite structure of the steel during hot rolling and optimizing the cold rolling and annealing processes. Especially in the production process to refine the carbonized structure and to cancel the grain orientation, while improving the formability and
