Nws muaj zoo heev thermal qaug zog tsis kam. Txawm hais tias nyob rau hauv cov xwm txheej ntawm qhov kub thiab txias, nws cov khoom siv hluav taws xob thiab oxidation tseem nyob ruaj khov, ua rau nws tsim nyog rau cov khoom siv hauv cov roj turbines thiab cov cua sov ua haujlwm nrog nquag pib- nce thiab kaw lub voj voog.
Zoo Fabrication thiab Vuam Properties
Haynes 188 muaj qhov kub thiab txias ua haujlwm tau zoo thiab tuaj yeem ua rau forged, dov, thiab tsim siv cov txheej txheem ib txwm ua. Nws muaj peev xwm ua tau zoo tshaj plaws thiab ua tau zoo nrog ntau yam kev siv vuam xws li Gas Tungsten Arc Vuam (GTAW), plasma vuam, thiab vuam vuam yam tsis tas yuav tsum tau tshwj xeeb tshaj tawm - vuam cua sov. Pa machining (tig, milling, drilling) yog siv tau; nyuaj hlau txiav cov cuab yeej raug pom zoo.
