Dab tsi yog tus qauv N08825?
Alloy 825, 2.4858, UNS N08825, Incoloy 825 - Nqe lus piav qhia
Alloy 825 (N{12}}8825) yog ib tug tswv cuab ntawm Ni-Cr-Fe-Mo tsev neeg ntawm alloys tsim nyob rau hauv 1950s. Nws muaj nominally 42% Ni, 32% Fe, 22% Cr, 2.5% Mo thiab 2% Cu, stabilized nrog 0.8% Ti, uas muab nws zoo heev tiv thaiv sulfuric acid thiab phosphoric acid. Lub alloy yog resistant rau ntau hom corrosion. Corrosive ib puag ncig thiab intergranular rhiab heev. Resistant rau oxidizing thiab txo cov kua qaub, SCC, pitting thiab intergranular corrosion rau siv nyob rau hauv tshuaj thiab petrochemical ua, roj thiab roj extraction, muaj kuab paug tswj, pov tseg kev kho mob thiab pickling daim ntaub ntawv.
Cov chaw thov
Alloy 825 yog siv nyob rau hauv phosphoric acid evaporators, pickling khoom, tshuaj ua cov hlab ntsha thiab pipelines, siv nuclear roj rov qab khoom, kiv cua shafts, thiab tank tsheb.
