Alloy 625 (UNS N06625) yog nickel-chromium-molybdenum alloy nrog ntxiv ntawm niobium. Qhov sib ntxiv ntawm molybdenum ua nrog niobium txhawm rau txhav cov hlau matrix, muab lub zog siab yam tsis muaj kev kho cua sov ntxiv. Lub alloy resists ntau yam corrosive ib puag ncig thiab muaj kev tiv thaiv zoo rau pitting thiab crevice corrosion. Alloy 625 yog siv rau hauv kev ua tshuaj lom neeg, aerospace thiab marine engineering roj & roj, cov cuab yeej tswj kev ua qias tuaj thiab nuclear reactors.
