5 Cov Lus Nug & Cov Lus Teb Txog Inconel 718 / UNS N07718 / GH4169 Round Bar

1. Dab tsi ua rau Inconel 718 / GH4169 haum rau siab -kev siv kub?

Teb:

Inconel 718 muaj npib tsib xee, chromium, thiab niobium, muab nws lub peev xwm los nag lossis daus.

Ua kom siab tensile, tawm los, thiab creep zog mus txog 700 degree.

Zoo heev oxidation thiab corrosion kuj, txawm nyob rau hauv acidic los yog saline ib puag ncig.

Zoo tagnrho rau aerospace turbines, siab -kub li qub, thiab kev siv nuclear.

2. UNS N07718 (Inconel 718) txawv li cas ntawm GH4169?

Teb:

UNS N07718 yog tus qauv tsim thoob ntiaj teb (ASTM / ASME).

GH4169 yog Suav teb chaws code rau tib yam khoom.

Ob leeg muaj tib yam tshuaj muaj pes tsawg leeg thiab txhua yam khoom.

Kev xaiv nyob ntawm qhov project specification lossis cov qauv hauv cheeb tsam.

3. Cov kev kho cua sov dab tsi feem ntau siv rau Inconel 718 round bars?

Teb:

Kev daws annealing: ~ 980-1,020 degree, ua raws li sai quenching kom yaj precipitates.

Kev laus / nag lossis daus hardening: ob npaug - theem kev laus (720℃rau 8 teev, txias, ces 620℃rau 8 teev) kom ua tiav qhov siab tshaj plaws tensile thiab yield zog.

Kev kho cua sov kom zoo ua kom muaj kev nkag siab, qaug zog, thiab tensile kev ua tau zoo rau siab -kev pabcuam kub.
