254 smo khoom yog dab tsi?
254 SMO yog lub siab -kawg austenitic stainless hlau uas muaj cov qib siab ntawm chromium, molybdenum, thiab nitrogen. Nws muaj kev tiv thaiv zoo heev rau pitting thiab crevice corrosion nyob rau hauv siab -chloride ib puag ncig ua rau nws yog ib qho zoo tagnrho lwm txoj rau nickel-raws li alloys thiab titanium nyob rau hauv daim ntawv thov xws li seawater kho, tshuaj ua, thiab pulp thiab ntawv manufacturing. Nws lub zog yog yuav luag ob npaug ntawm tus qauv 300 series stainless hlau.

254 SMO Stainless Hlau vs . 316 Stainless Hlau: Lub zog thiab Toughness
Lub zog tawm los ntawm 254 SMO yog qhov siab dua li ntawm 316 stainless hlau, ze li ob zaug siab. Qhov no txhais tau hais tias 254 SMO tsis tshua muaj kev cuam tshuam mus tas li hauv kev ntxhov siab. Qhov kawg tensile lub zog ntawm 254 SMO kuj yog me ntsis siab dua li ntawm 316.
254 SMO Stainless Hlau vs . 316 Stainless Hlau: Weldability
Ob leeg 254 SMO thiab 316 stainless hlau tuaj yeem welded siv cov txheej txheem vuam, tab sis 254 SMO xav tau kev saib xyuas ntau ntxiv kom tsis txhob muaj cua sov- thaj tsam cuam tshuam (HAZ) tawg.
Qhov txawv ntawm 254SMO thiab al6xn yog dab tsi?
AL-6XN muaj kwv yees li 5-10% lub zog ntau dua li 254 SMO thiab tseem ASME tau pom zoo txog 800℃F, whereas 254 SMO tau pom zoo txog 700℃F. AL-6XN tau raug xa mus rau P Number 45 hauv Tshooj IX ntawm ASME Boiler & Pressure Vessel code, Group 625 zoo li peb.
Dab tsi yog qhov txawv ntawm smo 254 thiab ss316?
SMO 254 yog lub siab- alloy stainless hlau nrog zoo corrosion kuj, lub zog thiab toughness vim nws cov ntsiab lus siab molybdenum. Nyob rau hauv sib piv, SS316 yog ib tug ntau ntau austenitic stainless hlau nrog zoo corrosion kuj nyob rau hauv ntau yam kev siv, tab sis nws cov kev ua tau zoo thiab lub zog nyob deb inferior rau SMO 254 nyob rau hauv hnyav los yog siab - chloride tej yam kev mob.
