Kev piav qhia ntawm Incoloy 825
Ob qho tseem ceeb tshaj plaws nickel alloys siv nyob rau hauv cov roj thiab roj kev lag luam yog incoly 825 yog cov oxoial 825 yog cov oxoial 825 yog cov oxoy-aws Qhov seem ntawm alloy cov ntsiab lus muab cov ntsiab lus zoo tshaj plaws rau cov chloride kev ntxhov siab corrosion thiab corrosion thiab dav corrosion thiab dav corrosion. Cov ntsiab lus txog nickel siab, nrog rau cov ntsiab lus siab thiab cov kab ntxwv tooj liab tau txhim kho cov kab uas muaj kev tiv thaiv corrosive, xws li muab tshuaj txo qis ib puag ncig, piv rau cov hlau stainless. Qhov sib ntxiv ntawm titanium rau cov allolo no tseem pab tswj cov alloy tawm tsam intergranular corrosion. Chloride kev ntxhov siab yog ib qho kev txhim kho hauv zos uas tshwm sim thaum cov khoom siv muaj pa thiab ib puag ncig muaj pa thiab c c c chloride ions, xws li dej hiav txwv.
Raws li cov Austenitic Nickel alloy, cov khoom siv yog du ntau qhov kub thiab txias ntau los ntawm cryogenic kom zoo dua 1000 degree f (538 degree). Lub tshuab xaws npib nyiaj npib yog cov alloys raug, thiab cov khoom siv tau yooj yim thiab muaj ntau yam ntawm cov tswv yim.

Nto Kho
# {{1 - kub kub quaj thiab descaled. Muaj nyob rau hauv sawb, Ntawv nyiaj thiab txoj hlua khi. Rau cov ntawv thov uas yog qhov chaw dai kom zoo nkauj tsis tas yuav tsum tau.
# 2d - npub npoo ua los ntawm txias dov, annealing thiab descaling. Siv rau kev sib sib zog nqus cov chaw thiab qhov chaw uas lubricants yuav tsum tau khaws cia thaum lub sijhawm tsim qauv. # 2b - du nto arcuced los ntawm txias dov, annealing thiab descaling. Ib lub teeb txias dov lub rolling dhau nrog cov yob polished tom qab annealing muab lub ntsej muag ci dua 2D.
# Ba- ci annealed colled thiab ci annaled
# Cba- ci ci annealed txias dov matte nto thiab ci ci annaled
# {2 -} txias dov
# 2ba- du nto uas tsim los ntawm txias dov thiab ci annealing. Lub teeb hla nrog cov yob polished heev ua rau muaj cov ntsej muag ci. Lub 2BA nto tuaj yeem siv rau lub teeb sib zog cov ntawv thov uas yuav tsum muaj cov npoo zoo nkauj yog qhov yuav tsum tau ua. Polishing - ntau yam kev ua kom haum rau cov kev yuav tsum tau ua.
