抗晶间腐蚀高强度全奥氏体电焊条
摘要：
一种抗晶间腐蚀高强度全奥氏体电焊条，CaO－CaF2－SiO2型碱性药皮渣系和Cr－Ni－Mo－Mn－N型合金系奥氏体焊条药皮，其焊条药皮组成：大理石45－55％，萤石16－25％，钛铁8－12％，硅铁1－5％，金属锰2－8％，钛白粉1－6％，纯碱1－3％，在药皮中还添加0.5－2.0％的氟化稀土；其焊条用焊芯的组成：C：0.03－0.12％，Si：0.2－0.7％，Mn：2.0－7.0％，S和P≤0.030％，Cr：15.0－19.5％，Ni：20－25％，Mo：4.0－7.0％，N：0.15－0.25％，V：0.15－0.3％，其余量为铁；将混合均匀的药粉用钠水玻璃作粘结剂压涂在焊芯上。
摘要（英）：

The invention relates to an anti-inter-crystal-corrosion high-strength austenite welding bar. Wherein, it is formed by CaO-CaF2-SiO2 alkali coat slag and Cr-Ni-Mo-Mn-N alloy austenite coat, while its coat comprises marble at 45-55%, 45-55% at 16-25%, ferrotitanium at 8-12%, ferrosilicium at 1-5%, manganese metal at 2-8%, titanium dioxide at 1-6%, soda at 1-3% and fluoride rare earth at 0.5-2.0%; and the welding bar comprises C at 0.03-0.12%, Si at 0.2-0.7%, Mn at 2.0-7.0%, S and P<=0.030%, Cr at 15.0-19.5%, Ni at 20-25%, Mo at 4.0-7.0%, N at 0.15-0.25%, V at 0.15-0.3%, and the left is iron, then the mixed powder is coated on the welding core via soldium-water glass as adhesive.
