Dab tsi yog cov thermal conductivity ntawm incoloy 825?
Alloy 825, 2.4858, tsis yog N08825, Incoloy 825 - Cov lus piav qhia
Alloy 825 (n 0 8825) yog ib qho alloy hauv tsev neeg Ni-Fe-Mo, tsim nyob rau xyoo 1950. It contains 42% Ni, 32% Fe, 22% Cr, 2.5% Mo, and 2% Cu, and is stabilized with 0.8% Ti, which gives it excellent resistance to sulfuric and phosphoric acids.
Lub alloy tiv taus ntau yam ntawm kev xeb ib puag ncig thiab cov sensgranular. Nws tiv thaiv oxidizing thiab txo cov kua qaub, kev nyuaj siab corrosion, roj thiab roj teeb, tswj kev paug, pov tseg
Cov Ntawv Thov
825 alloy yog siv hauv phosphoric acid evaporators, pipling cov khoom siv, siv cov khoom siv siv tshuaj lom neeg siv tshuaj lom neeg, cov khoom siv kiv cua
