stainless hlau qib 1.4404 vs . 1.4539 : sib txawv
Tso lus
SS 1.4539 khoom yog dab tsi?
SS 1.4539 yog super austenitic stainless hlau tseem hu ua 904L los yog UNS N08904, paub txog nws zoo heev corrosion kuj. Qhov no yog vim nws cov qib siab ntawm chromium, npib tsib xee, molybdenum, thiab tooj liab, uas ua rau nws tiv taus ntau yam acids thiab chloride ib puag ncig, thiab tseem tiv thaiv pitting, crevice, thiab kev ntxhov siab corrosion tawg.
Cov khoom siv twg yog 1.4539 sib npaug?
Cov khoom siv European tus qauv 1.4539 yog sib npaug rau 904L stainless hlau (AISI 904L) thiab UNS tsim N08904. Nws tseem hu ua X1NiCrMoCu25-20-5 nyob rau hauv lub npe EN/DIN. Lwm qhov sib npaug thoob ntiaj teb suav nrog SS 2562 (Swedish) thiab BS 904S13 (British).

1.4404 vs . 1.4539 Stainless Steel: Corrosion Resistance
Piv rau 1.4404 (316L), 1.4539 (904L) nthuav tawm cov kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig corrosive xws li sulfuric acid thiab siab - tshuaj chloride . 1.4404 qhia tau zoo corrosion kuj nyob rau hauv nruab nrab corrosive tej yam kev mob, thaum 1.4539 high corrosive daim ntaub ntawv.
1.4404 vs . 1.4539: Hardness
1.4539 yog me ntsis nyuaj dua 1.4404, nrog rau 1.4539 muaj ib tug raug hardness ntawm Less tshaj los yog sib npaug rau 230 HB thiab 1.4404 ntawm tsawg dua los yog sib npaug rau 215 HB. Txawm li cas los xij, ob qho tib si raug suav tias yog qhov muag muag piv rau lwm cov qib stainless hlau thiab feem ntau muaj nuj nqis rau lawv cov kev tiv thaiv corrosion es tsis yog siab hardness.
Qhov twg zoo dua, 904L lossis 316L?
Nyob rau hauv rooj plaub no, 904L stainless hlau yog qhov tseeb yeej tshaj 316L; nrog qhov nruab nrab PREN tus nqi ntawm 36.7, nws muaj zog ntau dua 316L (uas tsuas yog muaj PREN ntawm 26.1). Yog li ntawd, 904L feem ntau yuav tiv taus lub zog corrosive ntawm seawater.
Qhov txawv ntawm 1.4539 thiab 904L yog dab tsi?
1.4539 stainless hlau muaj cov ntsiab lus qis heev ntawm cov pa roj carbon tsawg thiab cov pa roj carbon tsawg kuj txhim kho qib qib corrosion kuj qib . 904L stainless tsis yog qib stainless hlau muaj zog heev thiab nws tsis muaj zog txhua yam khoom. 1.4539 tsis yog qib stainless hlau pheej yig thiab nws tsis yooj yim rau tshuab nws.
