316 thiab 316L stainless hlau:
316 thiab 316L stainless hlau yog molybdenum-cov kabmob stainless hlau qib. Cov ntsiab lus molybdenum hauv 316L stainless hlau yog me ntsis siab dua hauv 316 stainless hlau. Vim muaj cov molybdenum, cov qib no muaj tag nrho kev ua tau zoo dua piv rau 310 thiab 304 stainless hlau. Nyob rau hauv qhov kub thiab txias, 316 stainless hlau yog dav siv thaum lub concentration ntawm sulfuric acid qis dua 15% lossis siab dua 85%. 316 stainless hlau kuj tseem muaj kev tiv thaiv zoo rau chloride corrosion, ua rau nws nquag siv nyob rau hauv marine ib puag ncig. 316L stainless hlau muaj cov ntsiab lus siab tshaj plaws ntawm 0.03 thiab tuaj yeem siv rau hauv cov ntawv thov uas tsis tuaj yeem ua haujlwm tom qab vuam tsis tau thiab qhov siab tshaj plaws corrosion yuav tsum tau.
Chemical Composition: Thaum tshav kub kub Resistance: 316 stainless hlau muaj zoo oxidation kuj nyob rau hauv intermittent siv hauv qab no 1600 degrees thiab tsis tu ncua siv hauv qab no 1700 degrees. Nws tsis pom zoo kom tsis tu ncua nthuav tawm 316 stainless hlau nyob rau hauv thaj tsam ntawm 800-1575 degrees. Txawm li cas los xij, thaum siv tsis tu ncua sab nraum qhov ntsuas kub no, 316 stainless hlau muaj qhov ua kom sov zoo. 316L stainless hlau muaj kev tiv thaiv zoo rau carbide nag lossis daus dua 316 stainless hlau thiab tuaj yeem siv rau hauv qhov ntsuas kub tau hais tseg.
Kev kho cua sov: Annealing ntawm qhov kub thiab txias ntawm 1850-2050 degrees, ua raws li los ntawm annealing ceev thiab ceev txias. 316 stainless hlau tsis tuaj yeem hardened los ntawm overheating.
Vuam:
316 stainless hlau muaj cov khoom siv vuam zoo heev. Nws tuaj yeem welded siv txhua txoj kev vuam txheej txheem. Nyob ntawm daim ntawv thov, 316Cb, 316L, lossis 309Cb stainless hlau muab tub lim lossis electrodes tuaj yeem siv rau vuam. Yuav kom tau txais qhov zoo tshaj plaws corrosion kuj, welded seem ntawm 316 stainless hlau yuav tsum tau undergo tom qab vuam annealing. Yog tias siv 316L stainless hlau, tom qab vuam annealing tsis tas yuav tsum tau.
