Lub npe ntawm alloy 825 yog dab tsi?
Incoloy 825 alloy
Cov npe khoom lag luam: Incoloy 825, Alloy 825, Nickelvac 825, Nicrofer 4241.
INCOLOY Alloy 825 (UNS N08825, W.Nr. 2.4858) yog nickel-hlau-chromium alloy nrog ntxiv molybdenum, tooj liab, thiab titanium. Cov ntsiab lus npib tsib xee yog txaus los tiv thaiv chloride ion kev nyuaj siab corrosion cracking. Nickel, nrog rau molybdenum thiab tooj liab, kuj muaj kev tiv thaiv zoo heev los txo qhov chaw, xws li cov uas muaj sulfuric thiab phosphoric acids. Molybdenum kuj tseem pab tiv thaiv pitting thiab crevice corrosion. Lub alloy cov ntsiab lus chromium ua rau nws tiv taus ntau hom oxidizing, xws li nitric acid, nitrates thiab oxidizing ntsev. Nrog rau kev kho cua sov kom zoo, qhov sib ntxiv ntawm titanium tuaj yeem ua kom ruaj khov ntawm cov hlau thiab tiv thaiv intergranular corrosion rhiab heev.
Cov ntaub ntawv khoom muaj:
Cov yeeb nkab, raj, daim hlau, strips, daim hlau, puag ncig bar, tiaj tiaj, forgings, hexagonal tuav thiab hlau rods.
