style="text-indent:25px">不銹鋼封頭冷加工出現(xiàn)磁性的具體原因。其實(shí)，當(dāng)處于亞穩(wěn)定狀態(tài)的奧氏體不銹鋼進(jìn)行冷加工的時(shí)候，其中有一部分的奧氏體會(huì)發(fā)生馬氏體轉(zhuǎn)變，同時(shí)還會(huì)和原來(lái)的奧氏體保持共格。在實(shí)際工作中，我們通常會(huì)把這種以切變方式在極短時(shí)間內(nèi)發(fā)生的無(wú)擴(kuò)散相變，稱作致生馬氏體相變或者是形變誘導(dǎo)馬氏體相變。說(shuō)到這里，我們就需要對(duì)不銹鋼封頭產(chǎn)品所采用材料的結(jié)構(gòu)來(lái)進(jìn)行進(jìn)一步說(shuō)明。事實(shí)上，不銹鋼中馬氏體通常會(huì)包括兩種結(jié)構(gòu)形式，一種是有體心立方結(jié)構(gòu)的α’馬氏休，另一種是密集六方結(jié)構(gòu)的ε馬氏體。也就是說(shuō)，如果在加工不銹鋼封頭的時(shí)候，所采用的材料結(jié)構(gòu)不同的話，那么就可能會(huì)發(fā)生不同的情況。在這兩種不同形態(tài)中，其中第1種結(jié)構(gòu)的材料具有一定的磁性，而第二種結(jié)構(gòu)的材料不具有磁性。但是，如果鎳鉻含量較高的話，也會(huì)產(chǎn)生ε馬氏體。因此，我們就會(huì)明白，當(dāng)不銹鋼封頭的部分組織在進(jìn)行轉(zhuǎn)換的過(guò)程中，就會(huì)產(chǎn)生一定的磁性。通常情況下，奧氏體的穩(wěn)定性主要取決于其自身的化學(xué)成分。如果想要避免有磁性產(chǎn)生的話，應(yīng)當(dāng)更換材料，或者是進(jìn)行固溶處理。上海拱形封頭廠商封頭的安裝方式比較簡(jiǎn)單，不需要耗費(fèi)過(guò)多的時(shí)間。</p><div
