不銹鋼具有抵抗大氣氧化的能力---即不銹性，同時也具有在含酸、堿、鹽的介質(zhì)中耐腐蝕的能力，即耐蝕性。但其抗腐蝕能力的大小是隨其鋼質(zhì)本身化學組成、加互狀態(tài)、使用條件及環(huán)境介質(zhì)類型而改變的。如304鋼管，在干燥清潔的大氣中，有優(yōu)良的抗銹蝕能力，但將它移到海濱地區(qū)，在含有大量鹽份的海霧中，很快就會生銹了；而316鋼管則表現(xiàn)良好。因此，不是任何一種不銹鋼，在任何環(huán)境下都能耐腐蝕，不生銹的。不銹鋼是靠其表面形成的一層極薄而堅固細密的穩(wěn)定的富鉻氧化膜(防護膜)，防止氧原子的繼續(xù)滲入、繼續(xù)氧化，而獲得抗銹蝕的能力。一旦有某種原因，這種薄膜遭到了不斷地破壞，空氣或液體中氧原子就會不斷滲入或金屬中鐵原子不斷地析離出來，形成疏松的氧化鐵，金屬表面也就受到不斷地銹蝕。這種表面膜受到破壞的形式很多，常見的有如下幾種：1、不銹鋼表面存積著含有其他金屬元素的粉塵或異類金屬顆粒的附著物，在潮濕的空氣中，附著物與不銹鋼間的冷凝水，將二者連成一個微電池，引發(fā)了電化學反應，保護膜受到破壞，稱之謂電化學腐蝕。2、不銹鋼表面粘附有機物汁液（如瓜菜、面湯、痰等，在有水氧情況下），構(gòu)成有機酸，長時間則有機酸對金屬表面的腐蝕。泰州不銹鋼H型鋼公司-江蘇進百洪金屬制品有限公司。河北區(qū)不銹鋼H型鋼公司</p><p

氣候干燥通風好的環(huán)境不易生銹。而空氣濕度大，連續(xù)陰雨天氣、或空氣中含酸堿度大的環(huán)境地區(qū)就易生銹。304材質(zhì)不銹鋼，如果周邊環(huán)境太差也是會生銹的。四、不銹鋼就是不帶磁，不帶磁就是好不銹鋼嗎？如果微帶磁了就不是304了嗎？很多客戶到市場買不銹鋼，自身帶一塊小磁鐵，看貨時吸一下，認為吸不上的就是好不銹鋼。不帶磁就不會生銹了，其實這是一種錯誤的理解。不銹鋼帶不不帶磁是組織結(jié)構(gòu)決定的，鋼水在凝固過程當中由于凝固的溫度不同會形成“鐵素體”“奧氏體”“馬氏體”等不同組織結(jié)構(gòu)的不銹鋼，其中“鐵素體”“馬氏體”不銹鋼都是帶磁的。而“奧氏體”不銹鋼其綜合力學性能，工藝性能可焊性都好，但*從耐腐蝕性而言帶磁的“鐵素體”不銹鋼要強于“奧氏體”不銹鋼。目前市場流通的高含錳少含鎳的所謂200系列、300系列不銹鋼也不帶磁，數(shù)控微信公號cncdar但其性能與高含鎳的304的差距很大，反而，304經(jīng)過拉伸、退火、拋光、鑄造等工藝處理也會微帶磁性，因此用不銹鋼帶不帶磁來判斷不銹鋼的優(yōu)劣是一種誤解，也是不科學的。五、不銹鋼為什么也會生銹？當不銹鋼表面出現(xiàn)褐色銹斑（點）的時候，人們大感驚奇：認為“不銹鋼不會生銹的，生銹就不是不銹鋼了。河北區(qū)不銹鋼H型鋼公司</p><p
