style="text-indent:25px">不銹鋼管加工安裝不當(dāng)：一些不銹鋼加工商在做產(chǎn)品時(shí)，切割不銹鋼管或鐵的時(shí)候會(huì)將鐵屑飛濺到鋼管表面，如果不及時(shí)清理，會(huì)引起304不銹鋼管生銹。在粉刷墻壁或房屋之前安裝不銹鋼制品也會(huì)引起不銹鋼制品生銹。清潔保養(yǎng)不當(dāng)，在清理的過程中不可使用鋼絲球或者鋼絲刷去除不銹鋼管表面的水漬，因?yàn)檫@樣造成304不銹鋼管的表面劃傷，另外也要避免使用漂白成分以及研磨劑的洗滌液，包括含有酸堿性質(zhì)的洗潔精等洗滌劑，結(jié)束時(shí)再用清水沖洗304不銹鋼管表面。</p><p style="text-indent:25px">不銹鋼管普通常用布氏、洛氏、維氏三種硬度指標(biāo)來權(quán)衡其硬度。布氏硬度在不銹鋼管規(guī)范中，布氏硬度用處較廣，常常以壓痕直徑來表示該資料的硬度，既直觀，又便當(dāng)。但是關(guān)于較硬的或較薄的鋼材的鋼管不適用。洛氏硬度不銹鋼管洛氏硬度實(shí)驗(yàn)同布氏硬度實(shí)驗(yàn)一樣，都是壓痕實(shí)驗(yàn)辦法。不同的是，它是丈量壓痕的深度。洛氏硬度實(shí)驗(yàn)是當(dāng)前應(yīng)用很廣的辦法，其中HRC在鋼管規(guī)范中運(yùn)用僅次于布氏硬度HB.洛氏硬度可適用于測定由極軟到極硬的金屬資料，它補(bǔ)償了布氏法的不是，較布氏法煩瑣，可直接從硬度機(jī)的表盤讀出硬度值。304不銹鋼管的優(yōu)勢(shì)就是耐腐蝕性能。</p><div
