Inconel 718 Round Bar
Inconel 718 Bar muaj ob daim ntawv, ib qho yog lub xeev tom qab kev kho mob thiab lwm yam yog lub xeev tom qab nag lossis daus hardening. Thaum qhov kub nce mus txog 700 degree, nws yuav pom zoo tensile zog thiab tawg lub zog.
Khoom Taw qhia
Inconel 718 Round Bar muaj kev ua tau zoo thiab cov yam ntxwv, inconel 718 yog siv ntau yam kev siv forging los tsim cov khoom ntawm ntau yam duab, aviation thiab tsheb qhov chaw, dav hlau cav, marine turbines, thiab lwm yam.
Lub hardness ntawm tag nrho cov khoom kho cua sov tshwj tsis yog tias muaj lwm yam teev nyob rau hauv engineering daim duab yuav tsum yog tsawg kawg yog 36 HRC los yog sib npaug
Inconel 718 tuav, uas yog renowned rau lawv rupture, siab tensile, thiab cuam tshuam lub zog, kuj tso cai superior weldability. Tsis tas li ntawd, qhov kev sib xyaw ua ke no tuaj yeem siv rau hauv ntau qhov kub thiab txias li Inconel 718 puag ncig bar yog haum rau kev ua kom muaj kev kub ntxhov tshwj xeeb ntawm kev kub ntxhov thiab kev siv zog.
Microstructure
Inconel 718 bar yuav tsum yog austenitic nrog nplua tsis tu ncua precipitates ntawm carbides nyob rau hauv lub grain ciam teb thiab dispersed titanium carbonitrides. Metallographic kev tshuaj ntsuam ntawm cov ntoo khaub ncaws hla mus yuav tsum tsis muaj aliecanular, lossis lwm yam kev puas tsuaj loj dua}.} Mm hauv thickness, lossis ntau dua 0.025 hli rau cov khoom tshaj 1.50 hli thickness. Txhua tus qauv yuav tsum raug ntsuas ntawm 200x & 500x magnification.
