Stainless hlau 347H nta
347H yog ib qho kev siv roj chomium feem ntau siv nyob rau hauv kev ua kom zoo, kev siv hluav taws xob kub thiab txias. Cov kabmob columbium bear steel tsis rhiab rau intergranular corrosion tom qab cua nag los sis kev txhawb nqa tau los ntawm kev txo tus mob khaub thuas.
Tus "H" hauv 347h sawv rau "cov pa roj ntau". Qhov no ntau yam ntawm cov hlau stainless muaj ntau dua ntawm cov roj carbon ntau dua cov qauv ntawm lub zog 347 stainless lub zog thiab creeped tiv thaiv lub zog kub. Vim nws cov ntsiab lus carbon ntau dua, hom stainless hlau no muab kev ntxhov siab zoo dua li cov qauv. Nws tseem muaj qhov ua tau zoo rau oxidation nyob rau hauv cov kev pabcuam sib txawv txog 1600f thiab kev pabcuam txuas ntxiv mus txog 1700 degrees F.
