本研究中,我们开发了一种配套Q460MPa抗震耐蚀耐火钢使用的埋弧焊丝+焊剂组合,通过研究微合金元素的配比,使熔覆金属具备良好的力学性能,其强度大于常温2/3,-40℃冲击韧性大于52J,并且耐蚀性能与母材匹配。该数据为其熔敷金属的化学成分。
In this study, we developed a combination of submerged arc welding wire and flux for Q460MPa seismic and corrosion resistant refractory steel. By studying the ratio of microalloying elements, the cladding metal has good mechanical properties, with its strength greater than 2/3 at room temperature, impact toughness greater than 52J at -40℃, and corrosion resistance matching with the base metal. The data is the chemical composition of the metal deposited.
