style="text-indent:25px">除對尺寸精度、力學性能和表面狀態(tài)嚴格要求之外，不銹鋼精密鋼帶訂貨時還會對邊部處理進行約定。邊部狀態(tài)分為切邊（EC）、不切邊（EM）、磨邊（ER）三種邊部狀態(tài)。常涉及的指標為切邊鋼帶鐮刀允許值和鋼帶縱剪切邊毛刺高度。此外由于是鋼卷交貨，對鋼卷內(nèi)外徑、包裝單重和包裝方式也須事先溝通。不銹鋼精密鋼帶的標準此前國際國內(nèi)沒有統(tǒng)一的不銹鋼精密帶鋼標準，只有用于部分行業(yè)的專業(yè)標準，如日標JIS G4313《彈簧用不銹鋼冷軋鋼帶》等，使用過程頗為不便。基于此現(xiàn)狀，提出申請立項，并與冶金標準信息研究院共同起草編制了我國的第1部不銹鋼精密鋼帶標準，也是現(xiàn)行標準：YB/T 4432-2014 《不銹鋼精密鋼帶（片）》。</p><p
