Incoloy825适合采用任何传统焊接工艺与同种材料或其他金属焊接，如钨电极惰性气体保护焊、等离子弧焊、手工亚弧焊、金属极惰性气体保护焊、熔化极惰性气体保护焊，其中脉冲电弧焊是首选方案。在采用手工电弧焊时，推荐使用(Ar He H2 CO2)多种成份混合的保护气体。
Incoloy825的焊接必须在退火态进行，并使用不锈钢丝刷清理干净污渍、粉尘和各种记号。上海傲明实业有限公司在焊缝根部焊接时，为得到最佳的根部焊缝质量，操作必须非常小心(氩气99.99)，这样在根部焊接完后焊缝就不产生氧化物。焊接热影响区产生的颜色要在焊缝区域未冷却时用不锈钢刷刷去。
高镍成份使合金具有有效的抗应力腐蚀开裂性。在各种介质中的耐腐蚀性都很好，如硫酸、磷酸、硝酸和有机酸，碱金属如氢氧化钠、氢氧化钾和盐酸溶液。Incoloy825较高的综合性能表现在腐蚀介质多样的核燃烧溶解器中，如硫酸、硝酸和氢氧化钠都在同一个设备中处理。
(UNS N08825/W.Nr. 2.4858) is anickel-iron-chromium alloy with additions ofmolybdenum, copper, and titanium. The alloy’schemical composition, given in Table 1, is designed toprovide exceptional resistance to many corrosiveenvironments. The nickel content is sufficient forresistance to chloride-ion stress-corrosion cracking. Thenickel, in conjunction with the molybdenum andcopper, also gives outstanding resistance to reducingenvironments such as those containing sulfuric andphosphoric acids. The molybdenum also aids resistanceto pitting and crevice corrosion. The alloy’s chromiumcontent confers resistance to a variety of oxidizingsubstances such as nitric acid, nitrates and oxidizingsalt. The titanium addition serves, with an appropriateheat treatment, to stabilize the alloy againstsensitization to intergranular corrosion.
The resistance of INCOLOY alloy 825 to generaland localized corrosion under diverse conditions gives
the alloy broad usefulness. Applications includechemical processing, pollution control, oil and gas
recovery, acid production, pickling operations, nuclearfuel reprocessing, and handling of radioactive wastes.Applications for alloy 825 are similar to those forINCOLOY alloy 020.
