style="text-indent:25px">熱處理和精整工藝：精密不銹鋼帶的熱處理工藝與普通不銹鋼板的熱處理工藝基本相同，300系列奧氏體不銹鋼典型的熱處理工藝是固溶處理。在升溫過程中使碳化物溶入奧氏體，加熱到1050～1150℃，適當(dāng)保溫一段短時(shí)間，使碳化物全部溶解于奧氏體，然后迅速冷卻到350℃以下，得到過飽和固溶體即均勻的單向奧氏體組織。這一熱處理工藝的關(guān)鍵是快速冷卻，要求冷卻速度達(dá)到55℃／s，快速通過碳化物固溶后的再析出溫度區(qū)（550～ 850℃），保溫時(shí)間要盡量短，否則晶粒粗大，影響表面光潔度。強(qiáng)度較高的彈簧鋼，淬透性高，熱處理工藝性能好。彈簧鋼帶小型</p><p style="text-indent:25px">拉伸不銹鋼鋼帶：容易拉伸的不銹鋼帶，抗拉強(qiáng)度520，屈服強(qiáng)度205，拉伸率50%以上。彈簧鋼帶小型</p><p style="text-indent:25px">為了嚴(yán)格滿足不同用戶需求，精密鋼帶分等級(jí)進(jìn)行精度控制。尺寸達(dá)到很高的精度后，在力學(xué)性能上也要達(dá)到高精度的要求。常見的硬度狀態(tài)有：ANN、1/2H、3/4H、FH、EH 。粗糙度Ra是衡量表面狀態(tài)的重要指標(biāo)。精密不銹鋼帶的表面狀態(tài)對(duì)其外觀、性能、加工都有非常重要的影響。在所有冷軋板帶產(chǎn)品當(dāng)中，精密鋼帶的表面要求是較高的。工廠可以在軋制過程采用不同的工藝來控制表面粗糙度參數(shù)，使鋼帶具有更好的表面狀態(tài)以適應(yīng)不同領(lǐng)域的要求。帶鋼是各類軋鋼企業(yè)為了適應(yīng)不同工業(yè)部門工業(yè)化生產(chǎn)各類金屬或機(jī)械產(chǎn)品的需要而生產(chǎn)的一種窄而長(zhǎng)的鋼板。帶鋼又稱鋼帶，是寬度在1300mm以內(nèi)，長(zhǎng)度根據(jù)每卷的大小略有不同。彈簧鋼帶小型</p></p><br
