1.4404 vs . 1.4539: Corrosion kujcov
Piv rau cov1.4404 (316L), nws1.4539 (904L)Nws nthuav tawm cov kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav xws li sulfuric acid thiab kev daws teeb meem nrog cov ntsiab lus chloride siab. 1.4404 muaj kev tiv thaiv zoo nyob rau hauv nruab nrab corrosive tej yam kev mob, thaum 1.4539 yog tsim los rau siab corrosive daim ntaub ntawv.
1.4404 vs . 1.4539: Hardnesscov
Nws1.4539Nws yog me ntsis nyuaj dua1.4404, nrog ib tug raug hardness ntawm Less tshaj los yog sib npaug rau 230 HB piv rau Less tshaj los yog sib npaug rau 215 HB ntawm 1.4404. Txawm li cas los xij, ob qho tib si raug suav tias yog qhov muag muag piv rau lwm qib ntawm stainless hlau thiab muaj nuj nqis feem ntau rau lawv cov kev tiv thaiv corrosion es tsis yog lawv cov hardness siab.
1.4404 vs . 1.4539: Hom stainless hlau zoo tshaj rau cov saib?cov
Rau kev tsim cov watches, lub1.4539 (904L)feem ntau zoo dua1.4404 (316L), raws li nws cov nickel ntau dua thiab molybdenum cov ntsiab lus muab superior corrosion kuj, nrog rau cov chloride-induced pitting thiab kev nyuaj siab corrosion corrosion. Txawm hais tias 1.4404 muaj lub zog zoo heev rau lub hom phiaj dav dav thiab yog ib qho kev xaiv, kev txhim kho alloy ntawm 1.4539 ua rau nws yog cov khoom siv zoo tshaj plaws rau cov ntawv thov uas xav tau tshwj xeeb ua kom muaj zog thiab ua haujlwm nyob rau hauv ib puag ncig hnyav, xws li raug dej ntsev lossis tshuaj hnyav, uas muaj txiaj ntsig zoo rau kev saib xyuas.
