Muag li ob qho tib si Nickel Alloy 718 thiab Inconel 7l8, alloy 718 yog cov khoom siv muaj zog nickel-chromium. Qhov no muaj hnub nyoog-harden alloy muaj zoo heev corrosion-ua hauj thiab nthuav cov yam ntxwv uas ua rau nws yooj yim mus ua hauj lwm nrog rau fabrication lub hom phiaj. Lwm yam khoom tseem ceeb ntawm Nickel Alloy 718 thiab Inconel 7l8 yog:
- Zoo heev so tsis kam
- Yuav fabricated rau hauv txawm lub feem ntau complex qhov chaw
- Muaj qhov kub ntau ntawm -423 ° F (-253 ° C) txog 1300 ° F (705 ° C)
- Zoo heev tensile, qaug zog, creep, thiab rupture lub zog
- Gamma Prime muaj zog
- Zoo heev oxidation tsis kam mus txog 1800 ° F (980 ° C)
- Muaj nyob rau hauv annealed temper, hnub nyoog, txias ua hauj lwm, los yog txias ua hauj lwm thiab hnub nyoog
Vim nws cov khoom tshwj xeeb ntawm cov khoom, alloy 718 yog nrov nrog ntau yam kev lag luam tseem ceeb thiab kev siv xws li:
