316l daim iav tiav stainless hlau ntawv qhia
Kuj hu ua titanium hlau, 316L ss daim iav tiav stainless hlau.
Ntxiv Mo (2 ~ 3%) muaj qhov zoo heev pitting kuj thiab zoo heev kub creep zog.
316L yog molybdenum-muaj stainless hlau. Vim tias cov hlau muaj molybdenum, tag nrho cov kev ua tau zoo ntawm cov hlau no zoo dua li ntawm 310 thiab 304 stainless hlau. Nyob rau hauv qhov kub thiab txias, thaum cov concentration ntawm sulfuric acid qis dua 15% lossis siab dua 85%, 316L stainless hlau polished iav muaj ntau yam kev siv. . 316L stainless hlau kuj muaj kev tiv thaiv zoo rau chloride nres, yog li nws feem ntau yog siv rau hauv marine ib puag ncig. Cov ntsiab lus siab tshaj plaws ntawm 316L polishing hlau rau daim iav tiav tuaj yeem siv rau hauv cov ntawv thov uas tsis tuaj yeem ua tiav tom qab vuam qhuav thiab qhov siab tshaj plaws corrosion yuav tsum tau.

Daim ntawv thov ntawm 316l daim iav tiav stainless hlau ntawv
Qhov no stainless hlau yog ib tug kuj acid-resistant high-qib stainless hlau. Nws qhov txiaj ntsig loj tshaj plaws yog tias nws muaj molybdenum keeb, lub xub ntiag ntawm cov khoom no tuaj yeem txo cov cim siv lead ua corrosion ntawm stainless hlau thiab tuaj yeem tiv taus ntsev ntau dua. Hom stainless hlau no tuaj yeem siv los ua cov cuab yeej lossis kev phais thiab lwm lub sijhawm uas xav tau cov hlau tsis zoo. Nws kuj tuaj yeem siv rau cov kav dej, cov khoom siv hluav taws xob, cov khoom noj khoom haus, kev lag luam tshuaj, kev lag luam saib, thiab lwm yam.
Qhov zoo ntawm 316L stainless hlau
Corrosion kuj
Qhov kev tiv thaiv corrosion yog zoo dua li 304 stainless hlau, thiab nws muaj qhov zoo corrosion kuj nyob rau hauv cov txheej txheem ntawm cov ntaub so ntswg thiab ntawv. Thiab 316L stainless hlau kuj tseem tiv taus kev yaig los ntawm marine thiab aggressive industrial atmospheres.
kub tsis kam
Hauv kev siv sib cuam tshuam hauv qab 1600 degrees thiab siv tas li hauv qab 1700 degrees, 316L stainless hlau muaj qhov zoo oxidation tsis kam. Hauv qhov ntau ntawm 800-1575 degrees, nws yog qhov zoo tshaj kom tsis txhob ua tsis tu ncua. 316L stainless hlau, tab sis thaum siv tsis tu ncua sab nraum qhov kub thiab txias, 316L stainless hlau muaj cov cua sov zoo. Carbide nag lossis daus tsis kam ntawm 316L stainless hlau yog zoo dua li ntawm 316 stainless hlau, thiab qhov kub thiab txias saum toj no tuaj yeem siv tau.
Kev kho cua sov
Kev daws annealing yog ua nyob rau hauv qhov kub thiab txias ntawm 1010-1150 degrees, ua raws li qhov txias txias. 316L stainless hlau tsis tuaj yeem hardened los ntawm kev kho cua sov.
vuam
316L stainless hlau muaj zoo weldability. Txhua txoj kev vuam txheej txheem tuaj yeem siv rau vuam. Raws li daim ntawv thov, 316Cb, 316L lossis 309Cb stainless hlau muab tub lim lossis electrodes tuaj yeem siv rau vuam. Rau qhov zoo tshaj plaws corrosion kuj, welded seem ntawm 316 stainless hlau yuav tsum tau tom qab vuam annealing. Post weld annealing tsis tas yuav tsum yog 316L stainless hlau siv.
Cov yam ntxwv ntawm stainless hlau 316L daim iav vaj huam sib luag:
