Vim li cas thiaj xaiv 316 Stainless Hlau Welded Pipes?

Vim li cas thiaj xaiv 316 Stainless Hlau Welded Pipes

Vim tias qhov sib ntxiv ntawm molybdenum, 316 stainless hlau muaj kev tiv thaiv corrosion zoo heev, atmospheric corrosion kuj, thiab kub-siab zog, ua rau nws haum rau hnyav hnyav. Nws kuj muaj cov khoom ua haujlwm zoo hardening thiab tsis yog hlau nplaum.

• Corrosion Resistance

316 stainless hlau muaj superior corrosion kuj piv rau 304 stainless hlau thiab ua tau zoo nyob rau hauv zus tau tej cov pulp thiab ntawv. Tsis tas li ntawd, nws tiv thaiv corrosion los ntawm marine thiab aggressive industrial atmospheres.

Feem ntau, cov tshuaj tiv thaiv corrosion ntawm 304 thiab 316 stainless hlau zoo ib yam, tab sis muaj qhov sib txawv hauv ib puag ncig tshwj xeeb. Thaum pib, 304 stainless hlau tau tsim, tab sis nyob rau hauv qee qhov xwm txheej, nws yog rhiab heev rau pitting corrosion. Ntxiv 2-3% molybdenum txo qhov rhiab heev, ua rau kev txhim kho ntawm 316 stainless hlau. Cov molybdenum ntxiv kuj txo cov corrosion ntawm qee cov organic acids kub.

316 stainless hlau tau yuav luag dhau los ua cov khoom siv hauv kev lag luam zaub mov thiab dej haus. Vim tias lub ntiaj teb tsis txaus ntawm molybdenum thiab cov ntsiab lus nickel ntau dua hauv 316 stainless hlau, nws kim dua 304 stainless hlau.

Pitting corrosion yog feem ntau tshwm sim los ntawm deposits ntawm stainless hlau nto, tiv thaiv kev tsim ntawm ib tug tiv thaiv chromium oxide txheej vim tsis muaj oxygen.

Nyob rau hauv ntau yam dej xov xwm (dej distilled, dej haus, dej dej, boiler dej, seawater, thiab lwm yam), corrosion kuj ntawm 304 thiab 316 stainless hlau yog yuav luag tib yam, tshwj tsis yog thaum cov ntsiab lus chloride ion siab heev, nyob rau hauv cov ntaub ntawv no. 316 stainless hlau yog tsim nyog.

Feem ntau, qhov kev tiv thaiv corrosion ntawm 304 thiab 316 stainless hlau zoo ib yam, tab sis nyob rau hauv qee qhov xwm txheej, tuaj yeem muaj qhov sib txawv tseem ceeb uas yuav tsum tau txheeb xyuas cov ntaub ntawv los ntawm rooj plaub.

• Thaum tshav kub kub Resistance

316 stainless hlau muaj qhov zoo oxidation tsis kam nyob rau hauv kev sib tshuam kev pabcuam txog 1600 degree F (871 degree) thiab hauv kev pabcuam txuas mus txog 1700 degree F (927 degree). Nws yog qhov zoo tshaj kom tsis txhob siv 316 stainless hlau tsis tu ncua nyob rau hauv qhov 800-1575 degree F (427-857 degree) ntau yam, tab sis nws qhia tau hais tias muaj cua sov zoo thaum siv tsis tu ncua sab nraum qhov ntsuas kub no.
