            當前位置:如何選擇正確的不銹鋼焊材?
            [來源:www.phecda.org] [作者:精密鑄造] [日期:21-04-22]

            如何選擇正確的不銹鋼焊材?
            How to choose the right stainless steel welding material?
            如果母材是相同的,首要準則就是“與母材匹配”。例如焊接310或316不銹鋼,就選擇相應的焊材。
            If the base metal is the same, the first criterion is "match with base metal". For example, welding 310 or 316 stainless steel, select the corresponding welding material.
            焊接異種材料,則遵循選擇與合金元素含量高的母材相匹配的準則。例如焊接304和316不銹鋼,則選擇316型焊材。
            The selection criterion of high content of dissimilar elements should be followed. For example, if 304 and 316 stainless steels are welded, type 316 welding materials are selected.
            但是,也存在很多不遵循“匹配母材”原則的特殊情況,這時就要“查閱焊材選擇表”。例如,304型不銹鋼是最常見的母材,但是沒有304型的焊條。
            However, there are many special cases that do not follow the "matching base metal" principle, so it is necessary to "consult the welding material selection table". For example, type 304 stainless steel is the most common base metal, but there is no 304 type electrode.
            假如要焊材與母材匹配,如何選擇焊材來焊接304不銹鋼?
            If you want to match the base metal with the welding material, how to choose the welding material to weld 304 stainless steel?
            焊接304不銹鋼時,使用308型焊材,因為308不銹鋼中的額外元素可以更好的穩定焊縫區域。
            When welding 304 stainless steel, use 308 welding material, because the additional elements in 308 stainless steel can better stabilize the weld area.
            308L也是一個可接受的選擇。L表示低碳含量,3XXL不銹鋼表示碳含量≤ 0.03%,而標準的3XX不銹鋼可最高含有0.08%的碳含量。
            308L is also an acceptable option. L is low carbon content, 3xxl stainless steel is carbon content ≤ 0.03%, while standard 3xx stainless steel can contain up to 0.08% carbon content.
