GH4169 Siab-Tsub Alloy: Cov Khoom thiab Kev Siv
GH4169 Siab-Tsub Alloy: Cov Khoom thiab Kev Siv
GH4169 (UNS N07718) yog siv dav los nag los-nickel hardening-raws li superalloy (sib npaug rau Inconel 718) tsim los rau siab - qhov kub thiab txias ib puag ncig ntawm -253℃txog 650℃. Nws nthuav tawm lub zog tensile zoo heev, nkag siab tsis kam, thiab qaug zog qis dua 650 degree, nrog rau kev ua haujlwm zoo oxidation thiab weldability, ua rau nws cov khoom tseem ceeb rau lub tshuab aerospace, nuclear zog, thiab kev lag luam roj / roj.
Inconel 718 ua haujlwm li cas ntawm qhov kub thiab txias?
Inconel 718 yog nag lossis daus -nickel hardening-raws li alloy tsim los nthuav tawm lub zog siab heev, lub zog tensile, thiab creep rupture lub zog ntawm qhov kub txog li 1300℃F (700℃). Inconel 718 muaj lub hnub nyoog qeeb - cov lus teb nyuaj, yog li ntawd, kev ua kom tawv nqaij tsis tshwm sim thaum cua sov thiab txias, annealing, lossis vuam.
