      MWA特种钢氩弧焊丝MAC TRODE E66 TIG ER312


      Austenitic stainless steel filler metal originally designed to weld cast alloys of similar composition, found also valuable in welding dissimilar metals such as carbon steel to stainless steel, particularly those grades high in nickel. It gives a two-phase weld deposit with substantial percentages of ferrite in austenite matrix. Even with considerable dilution by austenite-forming elements such as nickel, the microstructure remains two-phase and thus highly resistant to weld metal cracks and fissures. Due to its high ferrite level, very adapted to heterogeneous welding, especially when one of the components is fully austenitic. Good corrosion oxidation resistance at high temperature due to its high content of Cr. Service temperatures should be below 420°C to prevent formation of secondary brittle phases.

      Mac Trode E66 TIG焊丝最初设计用于焊接成分相似的铸造合金,也适用于诸如碳钢与不锈钢(尤其是镍含量高)等之间的异种金属焊接。它可产生奥氏体基体中铁素体含量相当高的双相焊缝熔敷层。即使在奥氏体形成元素(如镍等)被大量稀释的情况下,微观结构仍然是双相的,对焊缝金属微裂纹和开裂仍具有很高的抵抗力。由于其铁素体含量高,非常适合异种焊接,尤其是当其中一个部件为完全奥氏体时。由于其铬含量高,在高温下仍具有良好的耐腐蚀氧化性。焊接时温度应低于420°C,以防止形成次生脆相。


      This grade may be essentially used for:


      1. l?welding of stainless steels with similar chemical composition;
      2. l?welding of dissimilar steels such as medium and high carbon steels to stainless steel;
      3. l?welding and facing of difficult-to-weld steels and unknown steels;
      4. l?buffering of layers on tooling prior to surfacing;
      5. l?wear facing, where resistance to severe impact is required.


      该款焊丝可用于:


      1. l?具有类似化学成分的不锈钢焊接;
      2. l?碳钢不锈钢等异种焊接
      3. l?难焊钢、未知钢的连接堆焊
      4. l 工具堆焊前缓冲层;
      5. l?要求耐严重冲击的耐磨堆焊


      TYPICAL APPLICATIONS 典型应用
