INCOLOY Alloy 825 (UNS N08825, W.Nr. 2.4858) se yon alyaj nikèl-fè-kwòm ak molybdène, kwiv, ak Titàn. Kontni nikèl la ase pou reziste klori ion estrès korozyon krak. Nikèl, ansanm ak molybdène ak kwiv, tou gen rezistans ekselan nan anviwònman diminye, tankou sa yo ki gen asid silfirik ak fosfò. Molybdène tou ede reziste pitting ak kreve korozyon. Kontni chromium alyaj la fè li rezistan a anpil espès oksidan, tankou asid nitrique, nitrat ak sèl oksidan. Avèk tretman chalè apwopriye, adisyon a nan Titàn ka estabilize alyaj la ak anpeche entèrgranulè sansibilizasyon korozyon.
Fòm pwodwi ki disponib:
Tiyo, tib, plak, bann, plak, ba wonn, ba plat, forgings, ba egzagonal ak fil fil.
