1. ASTM B637 yog dab tsi thiab yog vim li cas nws thiaj li cuam tshuam rau qhov no alloy bar?
Teb:
ASTM B637 yog tus qauv kev qhia tshwj xeeb uas npog npib tsib xee- puag alloy bars, forgings, thiab rings rau siab - kub thiab siab - siv zog. Nws ua kom ntseeg tau tias Inconel 718 bar ua tau raws li cov tshuaj muaj pes tsawg leeg, cov cuab yeej cuab tam, thiab cov txheej txheem tsim khoom.
2. UNS N07718 (Inconel 718) qhia dab tsi txog cov khoom siv?
Teb:
UNS N07718 yog hais txog Inconel 718, npib tsib xee-chromium alloy paub txog lub zog tensile zoo, qaug zog tiv thaiv, thiab corrosion kuj ntawm qhov kub thiab txias. Nws yog dav siv nyob rau hauv aerospace, roj turbines, thiab siab - kub yam ntxwv Cheebtsam.
3. Lub hom phiaj ntawm cov oxide dub ntawm lub bar yog dab tsi?
Teb:
Cov xim dub oxide tiav muab kev txhim kho corrosion, txheej tiv thaiv me me, txo lub teeb pom kev zoo, thiab zoo nkauj zoo nkauj. Nws kuj tseem pab tiv thaiv me ntsis ntawm oxidation thaum lub sij hawm cia.
4. Cov ntawv thov twg tsim nyog rau 28 hli txoj kab uas hla Inconel 718 bar?
Teb:
Lub 28 hli txoj kab uas hla bar feem ntau yog siv rau precision machined Cheebtsam xws li bolts, turbine shafts, fasteners, springs, thiab siab -kev ua tau zoo cav qhov chaw uas yuav tsum tau muaj zog thiab kub kuj.
5. Cov khoom siv dab tsi tuaj yeem xav tau los ntawm Inconel 718 bar ntsib ASTM B637?
Teb:
Cov khoom muaj xws li lub zog tensile siab (feem ntau siab dua 135 ksi / 930 MPa), zoo heev creep thiab qaug zog tiv thaiv, thiab muaj peev xwm tswj tau lub zog ntawm qhov kub txog li 700℃(1290℃F). Cov khoom no nyob ntawm qhov kev kho cua sov (xws li, tshuaj-annealed lossis hnub nyoog- hardened).
