Stainless hlau 347 Coil

Stainless hlau 347 Coil

Cov tshuaj lom neeg tseem ceeb ntawm 347 stainless hlau suav nrog 17-19% chromium, 9-13% nickel, thiab 0.08% carbon, nrog rau qee yam xws li titanium, niobium thiab molybdenum. Cov hlau stainless no tau siv dav hauv kev lag luam xws li tshuaj lom neeg, roj av, tshuaj thiab khoom noj khoom haus vim nws qhov kub thiab txias tsis kam, corrosion kuj thiab txhua yam muaj zog. 347 stainless hlau kuj muaj qhov zoo intergranular corrosion kuj thiab yog tsim rau siv nyob rau hauv kub kub.

347 Stainless Hlau Chev yog austenitic dov kauj stainless hlau uas ruaj khov los ntawm muaj niobium thiab tantalum. Ua ke, niobium (columbium) thiab tantalum cov ntsiab lus yog kaum npaug ntau dua li cov ntsiab lus carbon tam sim no. Zoo ib yam li Hom 321, Hom 347 muaj cov khoom zoo heev uas muaj zog tiv taus, nrog rau cov khoom muaj kev ntxhov siab ntau.

Nws muaj corrosion kuj zoo nyob rau hauv cov kua qaub, alkali thiab ntsev, thiab muaj oxidation tsis kam thiab weldability nyob rau hauv cov huab cua hauv qab no 800 degree. 347 stainless hlau muaj kev kub ntxhov siab rupture (Stress Rupture) kev ua tau zoo thiab kev kub ntxhov siab (Creep Resistance) kev ntxhov siab txhua yam khoom uas zoo dua li 304 stainless hlau. Siv dav hauv aviation, hluav taws xob tsim hluav taws xob, chemistry, petrochemical, zaub mov, ntawv thiab lwm yam.
