Al -6 xn (uns n08367) thiab 254 Smo, Daim Hlau & Coils Tus Nqe Sau, Qhov Coob & Cov Qauv Dawb!
Al -6 xn (uns ult (uns n08367) thiab 254 smo (uns uns31254)yog ob qho tib si siab-Molybdenum Super Austenitic stainless hlau, dav siv nyob rau hauv kev nyuaj siab ib puag ncig. Txawm hais tias cov tshuaj lom neeg muaj kuab lom thiab corrosion tsis kam ntawm ob yog zoo sib xws, muaj qhov sib txawv ntawm cov yam ntxwv tseem ceeb. Ht yeeb nkab yog n08367 thiabS31254 YeebCov chaw muag khoom nrog 15+ export kev paub.Tiv Tauj PebXav paub ntau ntxiv thiab hais rau DAWB!
Tshuaj Muaj Tshuaj
Lub chromium (~ 2 0%), Molybdenum (~ 6%) thiab nitrogen (~ 0.2%) cov ntsiab lus ntawm ob yog zoo sib xws, tab sis cov ntsiab lus tsib xee yog qhov sib txawv. Al -6 xn muaj txog 24% npib tsib xee, thaum 254 smo tsuas muaj 18%.
Corrosion Kuj Al -6 xn thiab 254 smo
Qhov pitting tiv taus (pre =}}}}}}}}}}}}}.
Vuam ntawm Al -6 xn thiab 254 smo
Thaum lub sij hawm vuam, molybdenum cov ntsiab lus ntawm al -6 xn Weld yog li 4% (6% Molybdenum) yog yuav tsum tau phim cov corrosion tsis kam. 254 Smo muaj cov ntsiab lus txog tsib qis, yog li cov txheej txheem vuam yog kev lag luam ntau dua.
Cov Khoom Siv Neeg Kho Tshuab
Cov txiaj ntsig ib lub zog (ntau dua los yog sib npaug nrog 300 mpa) thiab ntau dua lossis muaj zog dua li ntawm cov li 650] yog siab dua li ntawm cov neeg uas muaj hnub nyoog 2543] Ob qho tib si muaj ntau dua elongation (ntau dua los yog sib npaug rau 40%), tab sis al -6 xn muaj cov ntsiab lus txias dua vim nws cov ntsiab lus nitrogen siab dua.
Tus Qauv Kev Them Nqi ntawm Al -6 xn thiab 254 smo
254 smo muaj nyob rau hauv European Cov Qauv (en 1.4547) thiab ASTM, thaum Al {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}
Nqi thiab Kev Lag Luam Kev Lag Luam
254 Smo muaj cov ntsiab lus tsis muaj tsib xee tsawg, thiab nws tus nqi tsis tshua cuam tshuam los ntawm cov neeg tsib xee tus nqi hloov pauv, uas ua rau nws muaj txiaj ntsig zoo dua.
Cov ntawv thov raug
Al -6 xn: nws yog tsuas yog siv nyob rau hauv seaterwater cov nroj tsuag, licd) tso tsheb hlau taws (LND)
254 Smo: nws ua tau zoo nyob hauv seasater dej qab zib, tshwj xeeb yog nyob rau hauv scenarios khoom siv yog xav tau (thiab pulp kev nqus tau ntauwd), uas muaj ntau tsim yooj yim.
