产品特性DESCRIPTION

SW·ERNiCr-4焊丝用于Cr50Ni50镍铬合金的熔化极气体保护焊和钨极惰性气体保护焊，在镍铁铬钢管上堆焊镍铬合金以及铸件补焊。焊缝金属具有耐高温腐蚀、空气中含硫和矾的烟尘腐蚀的能力。

The SW·ERNiCr-4 welding wire is used for gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) of Cr50Ni50 nickel-chromium alloy. It is also applied in the surfacing of nickel-chromium alloy on nickel-iron-chromium steel pipes and the repair welding of castings. The weld metal possesses the ability to resist high-temperature corrosion as well as corrosion from sulfur-containing and vanadium-containing fumes in the air.

应用APPLICATIONS

用于焊接 Inconel 718、Incoloy 903 等沉淀强化型高温合金，如航空发动机涡轮盘、燃气轮机叶片等在 650-760℃长期工作，需承受高应力和热循环的部件。

It is used for welding precipitation-hardening superalloys such as Inconel 718 and Incoloy 903, including components like aero-engine turbine disks and gas turbine blades—parts that operate continuously at 650-760°C and need to withstand high stress and thermal cycles.
