    本閥門(mén)材質(zhì)選用表是用來(lái)大致指出與某種流體介質(zhì)接觸而發(fā)生反應(yīng)時(shí),應(yīng)如何選擇適當(dāng)?shù)牟牧。表中的推薦不是絕對(duì)的,因?yàn)樘间?鑄鐵,不銹鋼,青銅,蒙乃爾合金,哈氏合金,鈦,鈷鉻合金,沉淀鋼等閥門(mén)材料的耐腐蝕性與流體的濃度、溫度、壓力和雜質(zhì)等因素有關(guān)。因此,必須強(qiáng)調(diào)本表只能作為一個(gè)導(dǎo)則參考。
    符號(hào):
    A - 能夠或正被成功應(yīng)用
    B - 應(yīng)用過(guò)程應(yīng)注意
    C - 不能應(yīng)用
    LL - 缺乏資料
