Nkọwa nke Inconel 718

Inconel 718 Ngwa

Inconel 718 nwere ezigbo mmebi mmekpa ahụ na yang na-eguzogide na igwe jet na ngwa turbine gas. A na-eji alloy mee ihe maka akụkụ ndị chọrọ nguzogide dị elu na nrụgide nrụgide ruo 1300 ° F (704 Celsius C) na nkwụsị nke oxidation ruo 1800 ° F (982 ° C). Ọbụna na obere okpomọkụ, Injin Injin 718 nwere oke njigide na mmetụta metụtara. AMS 5662 chọrọ ikike mkpụrụ ≥ 150,000 psi na ụlọ okpomọkụ.
