Lub Npe STAINLESS 309

Apr 16, 2020

309 yog austenitic thaum tshav kub kub ua hauj alloy nrog oxidation tsis kam mus rau 1900 ° F nyob rau hauv qhov xwm kub. Thaum nquag ua kev thermal kev sib tw, cov xaim hluav taws ua haujlwm tiv taus txog 1850 ° F. Lub siab ntawm cov chromium thiab cov ntsiab lus qis ntawm cov lus qhia ntawm 309 muab qhov zoo tiv thaiv qhov kub thiab txias tshaj li cov pa roj carbon monoxide teeb meem.

Feem ntau hauv ntau cov khoom lag luam, cov nplej loj thiab cov ntsiab lus carbon yuav ua tau raws li ob qho ntawm 309 S thiab 309 H cov cai. Lub caij nyoog raug rau 1100-1600 ° F qhov kub thiab txias yuav ua rau qee tus sigma tsim, ua kom qis dua chav tsev kub ua haujlwm thiab cuam tshuam. Yuav tsum tsim kom muaj kev sigma, kev saib xyuas yuav tsum ua kom tsis txhob muaj qhov hnyav ntawm lub tshuab sov nyob rau chav sov. Pom zoo kom sov chav nyob. Weld nrog AWS E309-16 npog electrodes lossis ER 309 xaim xaim.
