ER308LSi yog stainless hlau welding hlau, belongs rau austenitic chromium-nickel steel vuam khoom qeb. Nws yog ib qho kev txhim kho ntawm ER308L, uas muaj cov pa roj carbon tsawg (feem ntau Tsawg dua lossis sib npaug li 0.03%) thiab siab silicon (silicon cov ntsiab lus feem ntau ntawm 0.65% thiab 1.00%).
Qhov kev tsim qauv tsim no ua rau lub pas dej zoo nkauj zoo nkauj thiab cov dej ntub dej thaum lub sijhawm vuam, ua kom zoo nkauj thiab zoo nkauj zoo nkauj, ua rau nws tsim tshwj xeeb rau cov ntawv thov uas yuav tsum muaj qhov zoo ntawm qhov zoo.
Nws yog tsuas yog siv rau vuam hom austenitic stainless hlau xws li 304, 304L, thiab 308L, thiab yog siv dav hauv kev lag luam xws li petrochemicals, kev ua zaub mov, khoom siv tshuaj, cov hlab ntsha siab, thiab kev tsheb nqaj hlau.
Nws cov hlau weld pom zoo corrosion kuj thiab txhua yam khoom; Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias yog lub hauv paus hlau dilution ua rau tag nrho cov austenitic los yog tsawg heev ferrite qauv nyob rau hauv lub vuam, nws kub cracking susceptibility yuav yog me ntsis siab dua li ntawm qhov tsawg tsawg - silicon vuam hlau.
Qhov vuam hlau no ua raws li ntau tus qauv thoob ntiaj teb, xws li AWS A5.9 ER308LSi thiab ASME SFA5.9.
