關(guān)于市場(chǎng)上流通的不銹鋼水箱材質(zhì)問(wèn)題
日期:2019-09-27 瀏覽量:9523

目前現階段市場(chǎng)上有很多水箱生產(chǎn)廠(chǎng)家使所謂的304二級料,這些料大部分都是南方的貨源。這種材料就是所謂的二級料,直白的說(shuō)就是說(shuō)是一些小鋼廠(chǎng)的不合格次品。

一級材料和二級材料主要區別是:表面、含鎳量、厚薄是否均勻等等......鋼廠(chǎng)處理后流落到市場(chǎng)的,真正的304一級材料便宜很多,使用這種二級材料做水箱質(zhì)量沒(méi)法保證,完全是在欺騙客戶(hù)。

現在發(fā)現市場(chǎng)上還出現了所謂的304J1的板材、304D的板材,不懂行的客戶(hù)也以為和304是同樣產(chǎn)品。具體其他區別都不談,單純說(shuō)說(shuō)304J1含有6%鎳,304D含有4%鎳。而正宗一級的304必須含有8%鎳以上的,如果說(shuō)用在水箱領(lǐng)域,那么水箱的防腐能力下降,焊接部分容易腐蝕,會(huì )大幅度影響水箱的使用壽命等,造成其它不可預計的嚴重財產(chǎn)損失。

本公司生產(chǎn)的華邦牌不銹鋼水箱,嚴格執行國家相關(guān)標準。采用正宗一級的304不銹鋼原材料制作水箱,為廣大客戶(hù)負責。
