Qhov sib txawv tseem ceeb ntawm Inconel 625 thiab 825 yog tias Inconel 625 muaj ntau cov npib tsib xee piv rau Inconel 825.
Inconel yog nickel-based superalloy. Peb tuaj yeem ntsuas qhov sib txawv ntawm cov hlau no, raws li cov nyiaj npib tsib xee tam sim no hauv cov hlau thiab txiav txim siab ntau lwm yam. Inconel 625 thiab Inconel 825 yog ob qib zoo li no. Qhov tseem ceeb tshaj, peb yuav tsum tsis txhob cuam tshuam nrog ob nqe lus Inconel thiab Incoloy; Txawm hais tias ob qho tib si no yog cov nickel-based alloys, lawv yog cov lag luam sib txawv nrog cov tshuaj sib txawv thiab lub cev.
Inconel 625 yog dab tsi?
Inconel 625 yog nickel-based superalloy uas muaj cov nickel ntau dua li lwm qib ntawm Inconel. Nws muaj lub zog siab thiab zoo heev resistivity rau siab dua kub. Ntxiv mus, nws qhia tau zoo heev tiv thaiv corrosion thiab oxidation. Cov khoom tshwj xeeb no ua rau nws muaj txiaj ntsig zoo hauv kev siv nuclear thiab marine.

Qhov kev pabcuam kub ntawm no superalloy ntau ntawm cryogenic rau 982 ° C. Lub zog siab ntawm cov hlau no yog vim lub zog ntawm molybdenum thiab niobium, uas nyob hauv cov nickel-chromium matrix. Yog li ntawd, qhov no alloy tsis xav tau los nag lossis daus hardening kev kho mob. Lub zog corrosion-siab qaug zog, siab tensile lub zog thiab kev tiv thaiv rau chloride-ion kev nyuaj siab-corrosion tawg ua rau cov hlau no yog ib qho kev xaiv zoo heev rau kev siv dej hiav txwv.
Sib nrug los ntawm qhov ntawd, Inconel 625 qhia tau hais tias muaj qhov ua tau zoo thiab tawv tawv ntawm qhov kub thiab txias. Thaum xav txog cov microstructure ntawm no alloy, nws yog ib tug solid-solution matrix-stiffened face-centred-cubic alloy. Ntxiv mus, cov hlau no muaj carbides nplua nuj nrog npib tsib xee, chromium, molybdenum, thiab lwm yam.
Inconel 825 yog dab tsi?
Inconel 825 yog nickel-based superalloy uas muaj cov nickel nruab nrab thaum piv rau lwm qib ntawm Inconel. Nws muaj cov ntsiab lus melting ntau dua tab sis muaj lub zog tensile tsawg thiab tsis muaj zog tawm los. Cov hlau no muaj nickel thiab chromium nrog rau molybdenum, tooj liab thiab titanium. Nws muaj qhov tshwj xeeb corrosion kuj tshwj xeeb, rau aqueous corrosion. Ntxiv mus, nws qhia tau hais tias tsis kam mus oxidizing thiab txo cov acids, xws li sulfuric acid, phosphoric acid, thiab lwm yam.
Qhov txawv ntawm Inconel 625 thiab 825 yog dab tsi?
Inconel 625 yog nickel-based superalloy uas muaj cov nickel ntau dua li lwm qib ntawm Inconel whereas Inconel 825 yog nickel-based superalloy uas muaj cov nickel nruab nrab thaum piv rau lwm qib ntawm Inconel. Qhov sib txawv loj ntawm Inconel 625 thiab 825 yog cov ntsiab lus nickel; Inconel 625 muaj txog 58% ntawm npib tsib xee thaum Inconel 825 muaj txog 36-48% ntawm npib tsib xee. Ntxiv mus, lawv muaj cov ntsiab lus melting sib txawv thiab. Lub melting point ntawm Inconel 625 yog 1350◦C, tab sis nws yog 1400◦C rau Inconel 825. Tsis tas li ntawd, lwm qhov sib txawv tseem ceeb ntawm Inconel 625 thiab 825 yog lawv lub zog; Inconel 625 muaj lub zog tensile siab heev thiab lub zog tawm los thaum piv rau Inconel 825.
Summary – Inconel 625 vs 825
Ob qho tib si Inconel 625 thiab 825 yog ob hom kev lag luam ntawm nickel-based superalloys. Lawv muaj nickel thiab chromium ua cov khoom tseem ceeb. Qhov sib txawv tseem ceeb ntawm Inconel 625 thiab 825 yog tias Inconel 625 muaj ntau cov npib tsib xee piv rau Inconel 825.
