采用高镍焊条焊接SA213—T—22,(21/4Cr—IMo)铁素体钢与321H(18Cr11Ni)奥氏体钢。采用高镍焊条焊接SA213一T一22,(2一1/4Cr一IMo)铁素体钢管与SA213-32一H(iserxrNi)奥氏体不锈钢管的接头,已有15年之久。用这种因科A型焊条解决了生产中的一大
SA213-T-22, (21 / 4Cr-IMo) ferritic steels and 321H (18Cr11Ni) austenitic steels were welded using high-nickel electrodes. It has been 15 years since high-nickel electrodes were used to weld joints SA213-T-22, (2-1 / 4Cr-1) ferritic steel and SA213-32-H iserxrNi austenitic stainless steel tubes. With this type of A-type electrode to solve the production of a large
