4. Nqe lus piav qhia:
AL6XN yog super austenitic stainless hlau nrog zoo heev tiv thaiv chloride pitting, crevice corrosion thiab kev nyuaj siab corrosion cracking.
AL6XN yog 6-molybdenum alloy tsim thiab siv nyob rau hauv ib puag ncig corrosive heev. Nws cov nickel siab (24%), molybdenum (6.3%), nitrogen
thiab cov ntsiab lus chromium muab nws zoo heev tiv thaiv chloride kev nyuaj siab corrosion cracking, chloride pitting thiab zoo heev corrosion kuj.
AL6XN feem ntau yog siv los txhim kho pitting thiab crevice corrosion ntawm chlorides. Nws yog ib qho kev tsim thiab weldable stainless hlau.
Vim nws cov ntsiab lus nitrogen, AL6XN muaj zog tensile ntau dua li cov austenitic stainless hlau zoo tib yam, thaum tswj siab ductility thiab cuam tshuam.
zog.
Corrosion kuj
Chromium, Molybdenum, Nickel thiab Nitrogen txhua tus pab txhawb rau tag nrho
Tiv thaiv corrosion ntawm ntau yam xov xwm. Chromium yog thawj tus neeg sawv cev rau imparting corrosion kuj nyob rau hauv nruab nrab los yog oxidizing ib puag ncig.
Chromium, molybdenum thiab nitrogen txhim kho pitting tsis kam. Nickel muab cov qauv austenitic. Ob leeg nickel thiab molybdenum muab
nce kev tiv thaiv rau chloride kev nyuaj siab corrosion cracking nyob rau hauv txo ib puag ncig.
5. Surface kev kho mob:
Qhov saum npoo ntawm stainless hlau yeeb nkab yog raws li nram no:
AP: Acid pickling (Anneal kho & Passivation) / (Acid pickling
MP: Mechanical sib tsoo lossis mechanical polishing (Mechanical Polish)
BA: Bright Anneal kev kho mob (Bright Annealing) EP: Electrolytic Polishing (Electro Polish)
