Corrosion Kuj Tseem Ceeb
In standard industrial environments, 304 stainless steel provides adequate protection against oxidation and mild chemical exposure. However, 316L demonstrates superior performance in more aggressive conditions. Salt spray testing shows 316L withstands chloride exposure 3-5 times longer than 304 before showing signs of pitting corrosion. For rotary unions handling seawater, Cov tshuaj ua kom dawb, lossis cov txheej txheem acidic ua kua, 316L yog qhov kev xaiv phy i} hauv cov khoom siv huv si thiab huv si ntawm cov khoom lag luam qis dua tus nqi qis dua tus nqi qis dua.}

Kev Txij Nkawm thiab Kev Ua Haujlwm Ntev
Proper material selection directly impacts service life and maintenance intervals. In moderately corrosive environments, 316L rotary unions typically last 2-3 times longer than 304 equivalents before requiring replacement. Both materials benefit from passivation treatments after machining to enhance their natural oxide layer. Regular inspection for signs of crevice corrosion is particularly tseem ceeb rau 304 lub tsev sib koom ua ke stainless hlau hauv cov chaw noo noo.
Kev Tawm Tsam Tawm Tshiab thiab Yav Tom Ntej Tiam
Thaum 304 thiab 316L tseem nyob ntawm cov qauv kev lag luam, kev kho cov txheej txheem hluav taws xob zoo li muaj lub zog ntawm ob qho tib si hauv lub zog ntawm ob peb xyoos.
