GH907 yog Fe-Ni-Co nag lossis daus hardening kub alloy nrog qis expansion thiab deformation, ntxiv dag zog nrog niobium, titanium, silicon thiab kab boron. Cov hlau muaj lub zog siab, qis coefficient ntawm kev nthuav dav, zoo ua haujlwm rau kub thiab txias qaug zog thiab yuav luag tas li modulus ntawm elasticity hauv qab 650 ° C. Curie point yog nruab nrab ntawm 400 ° C thiab 4000 ° C. Cov alloy muaj qhov qis expansion coefficient thiab zoo ua haujlwm rau kub thiab txias qaug zog. Curie point yog nyob rau hauv thaj tsam ntawm 400 ℃ -450 ℃. Lub coefficient ntawm expansion ntawm alloy yog qhov tseem ceeb tsis hloov hauv qab Curie point. Cov hlau yog tsim rau kev tsim txhua yam ntawm aviation thiab aerospace cav rings thiab cov ntawv xov xwm hauv qab 650 ℃, thiab cov khoom tseem ceeb muaj xws li tuav, forgings, daim hlau thiab strips. Txij li cov hlau tsis muaj chromium thiab txhuas cov ntsiab lus, qhov kub siab oxidation kuj tsis zoo. Thaum siv tau ntev tshaj li 700 ° C, cov txheej txheem tiv thaiv yuav tsum tau siv. Qhov saum npoo ntawm cov hlau tuaj yeem raug tua peened, uas txhim kho kev sib hloov bending qaug zog li ntawm 18%.
