1.4435 thiab 1.4961 Corrosion Resistance
316L: Vim nws cov ntsiab lus molybdenum, nws nthuav tawm zoo heev tiv thaiv chloride ion corrosion thiab zoo heev tsis kam rau pitting thiab crevice corrosion. Nws tuaj yeem tiv taus qhov hnyav corrosive ib puag ncig-xws li dej hiav txwv, siab - salinity ntsev tsuag, thiab 5% sulfuric acid- nrog rau txhua xyoo corrosion ntawm tsawg dua 0.01 hli. S1.4435 yog kev tiv thaiv rau intergranular corrosion tom qab vuam yam tsis xav tau kev kho cua sov tom qab.
347H:Nws tiv thaiv corrosion los ntawm huab cua huab cua, dej tshiab, thiab tsis muaj zog acids thiab cov hauv paus. Tsis muaj molybdenum, nws yog rhiab heev rau chloride ions thiab muaj qis pitting tsis kam piv rau 316L, txawm li cas los xij, nws cov ntsiab lus niobium zoo tiv thaiv kev cuam tshuam ntawm qhov kub thiab txias, thiab nws cov oxidation tsis kam tshaj ntawm qee yam austenitic stainless hlau.
1.4435 thiab 1.4961 Siab -Kev Ua Haujlwm Kub
316L:Haum rau ntev - qhov kev pab cuam kub txog li 600℃. Nws qhov siab - qhov kub thiab txias yog qhov nruab nrab, nws zoo li mos ntawm qhov kub siab tshaj 600℃thiab yog li tsis tsim nyog rau siab - qhov kub thiab txias - cov ntawv thov.
347H:Tshwj xeeb tsim los rau siab -kev siv kub, s1.4961 tuaj yeem tuav tau ntev - lub sijhawm ua haujlwm kub txog 800℃. Nws ua kom pom kev ua haujlwm zoo rau siab - qhov kub thiab txias rupture, tswj kev ruaj khov nyob rau hauv 540-815℃ntau yam, ua rau nws nyiam cov khoom siv boilers thiab siab -kub piping systems.
Stainless hlau 1.4435 thiab stainless hlau 1.4961Mechanical Properties
316L: Nta lub zog tensile ntawm Greater los yog sib npaug rau 485 MPa, lub zog tawm los ntawm ntau dua los yog sib npaug rau 170 MPa, thiab ib qho elongation ntawm Ntau dua los yog sib npaug rau 40%. Nws muaj cov yas zoo heev thiab weldability, yog yooj yim txias- tsim, thiab zoo - haum rau vuam complex qauv.
347H: Nws lub zog tensile thiab lub zog tawm los yog me ntsis siab dua li ntawm 316L, thiab nws nthuav tawm me ntsis hardness. Thaum nws cov plasticity thiab weldability yog qhov zoo, nws muaj qhov nyuaj dua me ntsis thaum lub sijhawm ua haujlwm txias, yuav tsum tau ceev faj txog kev ua haujlwm tsis zoo.
Vim li cas thiaj xaiv peb?
Peb muab siab -zoo 316L thiab 347H stainless hlau nyob rau hauv ib tug ntau yam ntawm specifications (phaj, raj, thiab yeeb nkab fittings). Peb cov khoom ua tau raws li National Standards thiab ASTM cov qauv, uas muaj cov tshuaj lom neeg muaj pes tsawg leeg thiab kev ua haujlwm ruaj khov, peb kuj txhawb kev sizing kom tau raws li koj cov kev xav tau tshwj xeeb.
