style="text-indent:25px">非標螺絲磁性特點：我們知道不銹鋼(不銹耐酸鋼)一般是不具磁性的，當我們在挑選不銹鋼f非標螺絲緊固件時，碰到一些有磁性的不銹鋼螺絲，是否可以表明不銹鋼螺絲是假冒的呢，或是品質(zhì)不良？實際不銹鋼材料品質(zhì)有分非常多種，其中鉻錳不銹鋼是具有磁性的不銹鋼。鉻錳不銹鋼也被稱為不銹鋼。它的化元素，除錳之外還有氮，一般還有適量的鎳。鋼中錳起穩(wěn)定{wending}的作用。由于氮強烈地形成并穩(wěn)定{wending}且起很好的固溶強化作用，提高了不銹鋼的強度，因此這個系列的不銹鋼，適宜在承受較重負荷而耐蝕性要求不太高的設備(shèbèi)和部件上使用。湖北非標螺絲批發(fā)商螺栓必須保持清潔，可適當添加潤滑劑。</p><div

style="text-indent:25px">非標螺絲主要運用于以下幾個方面：不銹鋼板、金屬鋼板、鍍鋅鋼板、工程安裝;金屬帷幕墻金屬輕隔間等室內(nèi)外安裝;一般角鋼、槽鋼、鐵板與其它金屬材料結(jié)合安裝;汽車車箱、貨柜箱、造船業(yè)、冷凍設備等組裝工程。非標螺絲鈍化處理到底有什么好處呢?因為在不銹鋼螺絲的生產(chǎn)過程中，特別是打頭和車削這些環(huán)節(jié)，螺絲的表面有可能會擦傷或者沾上一些細小的碎屑或顆粒，如果隨后進行熱處理，它的表面就有可能沾上氧化物質(zhì)。在鈍化的時候，不銹鋼螺絲會被浸入硝酸和水溶液中，取出的時候不銹鋼的表面會重新形成一層氧化薄膜，不會帶有外部物質(zhì)。螺絲如果沒有經(jīng)過清洗就暴露在外部環(huán)境下，就有很大可能會由于嵌入雜質(zhì)而生銹，因此為了得到更好的抗腐蝕性和更漂亮的外觀，很多不銹鋼螺絲都會做鈍化處理。</p><p style="text-indent:25px">電鍍的效果：電鍍的質(zhì)量以其耐腐蝕能力為主要衡量標準，其次是外觀。耐腐蝕能力即是模仿產(chǎn)品工作環(huán)境，設置為試驗條件，對其加以腐蝕試驗。電鍍產(chǎn)品的質(zhì)量從以下方面加以控制：1、外觀：制品表面不允許有局部無鍍層、燒焦、粗糙、灰暗、起皮、結(jié)皮狀況和明顯條紋，不允許有針眼麻點、黑色鍍渣、鈍化膜疏松、龜裂、脫落和嚴重的鈍化痕跡。2、鍍層厚度：非標螺絲在腐蝕性大氣中的作業(yè)壽命與它的鍍層厚度成正比。一般建議的經(jīng)濟電鍍鍍層厚度為0.00015in～0.0005in(4～12um).熱浸鍍鋅：標準的平均厚度為54um（稱呼徑≤3/8為43um），較小厚度為43um（稱呼徑≤3/8為37um）。鍍層分布：采用不同的沉積方法，鍍層在非標螺絲表面上的聚集方式也不同。電鍍時鍍層金屬不是均勻地沉積在外周邊緣上，轉(zhuǎn)角處獲得較厚鍍層。在非標螺絲的螺紋部分，較厚的鍍層位于螺紋牙頂，沿著螺紋側(cè)面漸漸變薄，在牙底處沉積較薄，而熱浸鍍鋅正好相反，較厚的鍍層沉積在內(nèi)轉(zhuǎn)角和螺紋底部，機械鍍的鍍層金屬沉積傾向與熱浸鍍相同，但是更為光滑而且在整個表面上厚度要均勻得多。當它們與水接觸時，它們會形成硫酸和氫氧化物，從而化學腐蝕不銹鋼螺栓。</p><div
