为适应化工炼厂发展的需要,鞍钢研制成功12Si MoVNbA1耐高温硫化氢腐蚀新钢种。为了推广使用该钢种,我所与天津电焊条厂、保定焊条厂合作,进行了配套焊接材料的研制,终于研制出Mo-W-Nb碱性低氢焊条。该焊条具有良好的综合机械性能,焊前可不预热,可焊性良好,焊接工艺成型美观,脱渣容易,飞溅小,可进行全位置焊接,并具有良好的抗氧化和耐硫腐蚀性能。
In order to meet the needs of chemical refinery development, Anshan Iron and Steel successfully developed 12Si MoVNbA1 high temperature hydrogen sulfide corrosion of new steel. In order to promote the use of the steel, I and Tianjin welding electrode factory, Baoding electrode factory cooperation, the development of supporting welding materials, and finally developed a Mo-W-Nb alkaline low hydrogen electrode. The electrode has good comprehensive mechanical properties, without preheating before welding, good solderability, good forming process of the welding process, easy slag removal, small spatter, full position welding and good anti-oxidation and sulfur-resistant corrosion resistance.
