產品簡介
Incoloy825適合採用任何傳統焊接工藝與同種材料或其他金屬焊接，如鎢電極惰性氣體保護焊、等離子弧焊、手工亞弧焊、金屬極惰性氣體保護焊、熔化極惰性氣體保護焊，其中脈衝電弧焊是首選方案。在採用手工電弧焊時，推薦使用(Ar+He+H2+CO2)多種成份混合的保護氣體。
Incoloy825的焊接必須在退火態進行，並使用不鏽鋼絲刷清理乾淨污漬、粉塵和各種記號。上海傲明實業有限公司在焊縫根部焊接時，為得到最佳的根部焊縫質量，操作必須非常小心(氬氣99.99)，這樣在根部焊接完後焊縫就不產生氧化物。焊接熱影響區產生的顏色要在焊縫區域未冷卻時用不鏽鋼刷刷去。
高鎳成份使合金具有有效的抗應力腐蝕開裂性。在各種介質中的耐腐蝕性都很好，如硫酸、磷酸、硝酸和有機酸，鹼金屬如氫氧化鈉、氫氧化鉀和鹽酸溶液。Incoloy825較高的綜合性能表現在腐蝕介質多樣的核燃燒溶解器中，如硫酸、硝酸和氫氧化鈉都在同一個設備中處理。
(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.
