310S stainless hlau muaj oxidation zoo thiab corrosion kuj. Vim muaj cov ntsiab lus siab ntawm chromium thiab npib tsib xee, zoo corrosion kuj thiab zoo kub tsis kam, nws tuaj yeem siv li ntawm 1100 degree. Lawv txhua tus yog siv rau hauv boilers, lub zog (nuclear zog, thermal zog, roj hlwb), industrial furnaces, incinerators, cua sov furnaces, tshuaj lom neeg kev lag luam, petrochemical kev lag luam thiab lwm yam tseem ceeb teb. Vim muaj cov ntsiab lus siab ntawm chromium thiab npib tsib xee ntsiab lus, zoo corrosion kuj thiab zoo tshav kub kuj, qhov siab tshaj plaws siv kub yog txog 1100 degree.
Cov ntsiab lus chromium hauv 309S yooj yim tsim CR20 oxide zaj duab xis ntawm qhov kub thiab txias. Lub diffusion ntawm nickel ntsiab tsis pom tseeb ntawm qhov kub thiab txias, tab sis ntawm 1000 degree, tib qhov tshwm sim diffuses rau saum npoo. Thaum cov oxide zaj duab xis no sib npaug ntawm qhov chaw ntawm cov hlau matrix, ntxiv oxidation ntawm cov hlau tuaj yeem tiv thaiv, thiab cov yeeb yaj kiab muaj kev tiv thaiv zoo. Qhov no yog qhov laj thawj tseem ceeb vim li cas 309S muaj kev tiv thaiv zoo rau kev kub siab oxidation.
Kev ua haujlwm siab kub: 310S stainless hlau muaj qhov kub thiab txias zoo dua thiab tuaj yeem siv tau ntev hauv qhov kub thiab txias, nrog rau qhov siab tshaj plaws siv kub txog 1100 degree; 309S stainless hlau muaj nruab nrab kub tsis kam, nrog rau qhov siab tshaj plaws siv kub yog txog 1000 degree.
Corrosion kuj: 310S stainless hlau muaj corrosion kuj zoo rau oxidizing, txo thiab nruab nrab gases, thiab kuj yog resistant rau kub thiab muaj zog acid thiab alkaline ib puag ncig; 309S stainless hlau muaj qhov kub thiab txias corrosion kuj, tshwj xeeb tshaj yog rau cov acids muaj zog xws li sulfuric acid thiab nitric acid.
Kev ua tau zoo: 310S stainless hlau muaj qhov zoo weldability thiab plasticity, thiab tuaj yeem ua tiav los ntawm ntau txoj kev ua cov pa; 309S stainless hlau kuj muaj qhov zoo weldability thiab plasticity, thiab tuaj yeem welded los ntawm cov txheej txheem vuam xws li hluav taws xob vuam thiab roj vuam.
