Yuav ua li cas yog corrosion kuj ntawm 1.4401 stainless hlau?
1.4401 (AISI 316) stainless hlau muaj kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog nyob rau hauv chloride- nplua nuj thiab marine ib puag ncig, vim nws cov ntsiab lus 2-3% molybdenum. Nws ua tau zoo tshaj tus qauv 304 (1.4301) steel tiv thaiv pitting thiab crevice corrosion, ua rau nws zoo tagnrho rau kev ua tshuaj, ntug hiav txwv dej, thiab kev siv tshuaj.
Weldability ntawm 1.4401 stainless hlau
1.4401 (AISI 316) stainless hlau qhia tau zoo heev weldability hla cov txheej txheem vuam ntau-xws li TIG (GTAW), MIG (GMAW), thiab SAW- thiab feem ntau yuav tsum tsis muaj kev tshaj tawm -weld heat treatment. Nws cov ntsiab lus tsis tshua muaj carbon (tsawg dua lossis sib npaug li 0.08%) txo qis kev cuam tshuam rau intergranular corrosion, ua rau nws tshwj xeeb tshaj yog haum rau cov khoom siv uas muaj kev tiv thaiv corrosion yog qhov tseem ceeb.
Puas yog 1.4401 stainless hlau sib nqus?
1.4401 (AISI 316) stainless hlau feem ntau tsis yog -sib nqus hauv nws lub xeev annealed. Raws li cov hlau austenitic nrog cov nickel thiab molybdenum siab, nws feem ntau tsis nyiam cov hlau nplaum. Txawm li cas los xij, nws tuaj yeem pom cov hlau nplaum tsis muaj zog heev tom qab ua haujlwm txias (khoov, txiav, lossis sib sau) vim qhov hloov pauv martensitic ib nrab.
