GH4049 (GH49) kub kub alloy yog lub hnub nyoog-hardening npib tsib xee-raws li kub kub alloy muaj li ntawm npib tsib xee, molybdenum, txhuas thiab lwm yam ntsiab lus, nrog ib tug nickel ntsiab lus ntawm txog 70%. GH4049 kub kub alloy muaj qhov kub thiab txias ua haujlwm zoo, siab kub lub zog qis dua 950 degree, tsis tshua muaj siab rhiab heev, zoo oxidation tsis kam thiab qaug zog, thiab tsis zoo ib yam kub ua plasticity. Nws cov txheej txheem kub kub tuaj yeem txhim kho los ntawm lub tshuab nqus tsev siv lossis electroslag remelting.

Cov khoom ntawm GH4049 alloy
GH4049 alloy yog kub-kub alloy nrog kev ua tau zoo heev thiab ntau yam kev siv. Ua ntej ntawm tag nrho cov, GH4049 alloy muaj qhov kub thiab txias tsis kam thiab tuaj yeem tswj cov khoom siv hluav taws xob thiab tshuaj lom neeg ruaj khov hauv qhov chaw kub kub. Nws cov oxidation zoo heev tuaj yeem tiv taus oxidation thiab corrosion nyob rau hauv high-temperature atmospheres thiab tswj cov stability ntawm cov khoom. Qhov no ua rau GH4049 alloy dav siv nyob rau hauv high-kub teb xws li aerospace thiab petrochemicals. Qhov thib ob, GH4049 alloy muaj cov khoom siv zoo. Nws muaj lub zog siab thiab hardness thiab tuaj yeem tiv taus cov khoom hnyav ntawm qhov kub thiab txias. Nyob rau tib lub sijhawm, nws kuj muaj qhov zoo toughness thiab qaug zog tiv thaiv, thiab tuaj yeem tswj kev ua haujlwm ruaj khov hauv kev siv mus ntev. Qhov no ua rau GH4049 alloy yog cov khoom siv zoo tshaj plaws rau kev tsim cov khoom kub. Tsis tas li ntawd, GH4049 alloy kuj muaj qhov zoo corrosion kuj. Nws tuaj yeem tiv taus qhov yaig ntawm ntau yam corrosive media xws li acids, alkalis, thiab ntsev, thiab muaj kev tiv thaiv corrosion siab. Qhov no ua rau GH4049 alloy dav siv nyob rau hauv corrosive ib puag ncig xws li tshuaj lom neeg kev lag luam thiab dej hiav txwv.
