Qhov sib txawv ntawm 1.4401 thiab 1.4404 stainless hlau

Ntawm ntau hom stainless hlau, cov corrosion-resistant Austenitic stainless hlau 1.440 thiab 1.440 tau nyiam ntau. Nrog lawv cov khoom muaj txiaj ntsig, lawv ua ib lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam.

Ob phau 1.440 thiab 1.4401 muaj 2 - 2. 5% molybdenum kam, ntsuas kub, colorine tsis kam thiab dej hiav txwv. Ntawm lawv, 1.440 yog ib tug ultra-tsawg cov roj carbon-tsawg cov roj carbon aus roj stainless hlau, uas ua rau nws zoo heev hauv kev txhim kho corrosion, deb tshaj 1.4401 stainless hlau.

Intergranular corrosion yog ib qho teeb meem ntsib los ntawm 1.4401 stainless hlau. Thaum nws raug rau kub hauv thaj tsam ntawm {2}} degree, chromium carbides, uas yuav ua rau muaj ciam chaw hauv corrosion. Vim nws cov ntsiab lus muaj roj teeb qis, 1.4404 Stainless hlau tau dhau los ua qhov kev xaiv tseem ceeb rau cov ntawv thov tsis tuaj yeem qhia ntxiv tom qab vuam. Rau cov xwm txheej uas ntxhov siab tso tawm ntawm qhov chaw kub qis yog qhov yuav tsum tau lossis qhov twg nws yuav raug luv luv ntawm {}} degree, 1.440 kuj tseem tuaj yeem tiv thaiv nws yooj yim.

Thaum 1.4404 / 1.4401 stainless hlau yog daws anealed, nws yuav tsum tau ua kom sov rau {}} degree thiab tom qab ntawd nyob ntawm qhov loj ntawm qhov loj ntawm lub workpiece.

1.4401 Stainless Austenitic hlau yog dav siv nyob rau hauv kev lag luam tshuaj, ntsuas engineering, pulp kev lag luam thiab kev lag luam khoom noj. 1.4404 (316L) Austenitic Stainless hlau tsis yog tsuas yog tiv taus cov kua qaub, tab sis kuj siv cov cuab yeej siv tshuaj, dej pheeb suab.
