style="text-indent:25px">不銹鋼帶和其他材料一樣，物理性能主要包括以下3個方面：熔點、比熱容、導(dǎo)熱系數(shù)和線膨脹系數(shù)等熱力學(xué)性能，電阻率、電導(dǎo)率和磁導(dǎo)率等電磁學(xué)性能，以及楊氏彈性模量、剛性系數(shù)等力學(xué)性能。這些性能一般都被認為是不銹鋼材料的固有特性，但是也會受到諸如溫度、加工程度和磁場強度等的影響。通常情況下不銹鋼與純鐵相比導(dǎo)熱系數(shù)低、電阻大，而線膨脹系數(shù)和導(dǎo)磁率等性能則依不銹鋼本身的結(jié)晶結(jié)構(gòu)而異。物理性能與溫度的相關(guān)性比熱容，隨著溫度的變化比熱容會發(fā)生變化，但在溫度變化的過程中金屬組織中一旦發(fā)生相變或沉淀，那么比熱容將發(fā)生明顯的變化。冷軋彈簧鋼帶訂購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。</p><div

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℃），保溫時間要盡量短，否則晶粒粗大，影響表面光潔度。</p><p style="text-indent:25px">熱軋彈簧鋼材有圓鋼、方鋼、扁鋼等。鋼材表面質(zhì)量要求較高，可以熱軋態(tài)交貨或者經(jīng)熱處理后交貨，以保證硬度不超過規(guī)定值，便于制簧。熱軋材可以冷態(tài)制成螺旋彈簧，對于截面尺寸較大者需加熱后制成彈簧。彈簧成型后再經(jīng)淬火、中溫回火，回火溫度約為350～550℃，以獲得較高屈強比和良好的綜合力學(xué)性能。因熱軋材截面尺寸較大，故應(yīng)采用淬透性足夠高的牌號，保證心部淬透。若心部出現(xiàn)非馬氏體轉(zhuǎn)變產(chǎn)物，如鐵素體、貝氏體等，則回火后的性能降低，特別是疲勞性能。冷拉（軋）彈簧鋼材包括鋼絲、鋼帶。這類鋼材的表面質(zhì)量和尺寸精度要求格外嚴格。鋼絲的生產(chǎn)工藝有油淬火和冷拉兩種。熱軋材可以冷態(tài)制成螺旋彈簧，對于截面尺寸較大者需加熱后制成彈簧。</p><div
