Lub cev muaj zog ntawm 347 Stainless hlau kav
Lub cev lub cev ntawm Hom 321 thiab 347 yog qhov zoo sib xws thiab, rau txhua lub hom phiaj, yuav raug suav hais tias yog tib yam. Cov txiaj ntsig tau muab rau hauv lub rooj tuaj yeem siv los siv rau ob qho tib si steels.
Thaum annealed kom zoo, Alloys 321 thiab 347 stainless hlau muaj feem ntau ntawm austenite thiab carbides ntawm titanium los yog columbium. Me me ntawm ferrite tej zaum yuav los yog tsis muaj nyob rau hauv lub microstructure. Cov theem me me ntawm sigma tuaj yeem tsim thaum lub sij hawm ntev raug nyob rau hauv 10000F txog 15000F (5930C txog 8160C) kub ntau.
Lub stabilized Alloys 321 thiab 347 stainless hlau tsis hardenable los ntawm kev kho cua sov.
Tag nrho cov tshav kub hloov coefficient ntawm hlau yog txiav txim los ntawm cov yam tseem ceeb ntxiv rau thermal conductivity ntawm hlau. Feem ntau, zaj duab xis coefficients, scaling, thiab deg tej yam kev mob yog xws li hais tias tsis ntau tshaj 10 mus rau 15 feem pua ntau qhov chaw saum npoo yog xav tau rau stainless hlau dua li lwm cov hlau uas muaj thermal conductivity ntau dua. Lub peev xwm ntawm cov hlau tsis muaj steel los tuav cov chaw huv si feem ntau tso cai rau kev hloov pauv kom zoo dua li lwm cov hlau uas muaj thermal conductivity ntau dua.
