Cov ntawv ntawm AL-6XN Muaj
• Ntawv
• Phaj
• Bar
• Yeeb& Txoj raj (welded& seamless)
• Cov khoom siv (xws li flanges, plam-ons, dig muag, caj dab-caj dab, ncej puab, caj dab ntev ntev, txuas lub qhov taub, lub lauj tshib, tees, txhav kawg, rov qab, lub kaus mom, hla, reducers, thiab cov leeg ntawm lub raj mis)
AL 6 XN Txheej txheem cej luam
AL 6 XN yog superaustenitic stainless hlau nrog zoo heev tiv taus chloride pitting, crevice corrosion thiab kev nyuaj siab corrosion tawg. AL 6 XN yog ib qho 6 moly alloythat tau tsim rau thiab siv rau hauv qhov chaw muaj kev ntxhov siab heev. Nws muaj npib tsib xee siab ({{3}}%), molybdenum (6. , thiab qhov tshwj xeeb dav corrosion tsis kam. AL 6 XN feem ntau yog siv rau nws txoj kev txhim kho pitting thiab txoj kev lag luam corrosion tiv thaiv hauv chlorides. Nws yog ib daim hlau uas tsim tau thiab weldable stainless hlau.
Vim tias nws cov ntsiab lus hauv nitrogen, AL 6 XN muaj ntau dua lub zog tensile dua li cov austentitic stainlesses, thaum khaws cia siab ductility thiab cuam tshuam lub zog.
Corrosion kuj
Chromium, molybdenum, npib tsib xee thiab nitrogen txhua tus pab txhawb kom muaj kev xeb tuaj yeem tiv thaiv kev xeb los ntawm ntau yam xov xwm. Chromium yog tus neeg sawv cev tus thawj coj rau kev tsis kam xeb rau hauv qhov chaw nruab nrab lossis oxidizing ib puag ncig. Chromium, molybdenum thiab nitrogen nce ntxiv tiv taus pitting corrosion. Nickel imparts tus qauv austenitic. Nickel thiab molybdenum ob qho tib si muab qhov muaj peev xwm tiv taus chloride kev nyuaj siab corrosion rau kev txo cov ib puag ncig.
Dab tsi yog AL-6XN tus yam ntxwv?
• Cov tshuaj tiv thaiv zoo rau kev pitting thiab kev xeb hauv kev daws teeb meem chloride
• Kev tiv thaiv tsis muaj zog tiv thaiv kev ntxhov siab corrosion hauv NaCl ib puag ncig
• Lub zog muaj zog thiab tawv toughChemical Composition,%
