Sehlahisoa SEHLOOHO
GH99 ke Ni-Cr e thehiloeng ho pula e thatafatsang deformation e phahameng ea mocheso, e ka sebelisoang nako e telele ka tlase ho 900 ° C, 'me mocheso o phahameng oa nako e khutšoanyane oa tšebeletso o ka fihla ho 1000 ° C. GH99 alloy e matlafatsoa ke ho eketsoa ha chromium, cobalt, tungsten le molybdenum bakeng sa ho matlafatsa tharollo e tiileng, ka ho eketsoa ha aluminium le titanium ho theha mekhahlelo ea botsofali, le ka ho eketsoa ha boron, cerium le magnesium ho hloekisa le ho matlafatsa meeli ea lijo-thollo. GH99 alloy e na le matla a phahameng a mocheso, mokhatlo o tsitsitseng, 'me e na le mokhoa o khotsofatsang oa ho etsa mochine o chesang le o batang le ts'ebetso ea ts'ebetso ea welding.GH99 e loketse ho etsoa ha likamore tse tukang ka enjene ea aero-enjene le likamore tse tukang peterole le likarolo tse ling tsa sebopeho se cheselitsoeng ka mocheso o phahameng.Lihlahisoa tse ka sehloohong tsa GH99 tsa li-platelete tsa GH99 le li-hotsers. Ka motsoako o entsoeng ke sebopeho se seholo sa poleiti, se ka sebelisoa ka ho toba ka mor'a tharollo e tiileng Phekolo ntle le botsofali Phekolo. Alloy ka 700 ℃ ~ 950 ℃ botsofali ba nako e telele ha boa ka ba fumana mekhahlelo e kotsi.
