Qhov zoo ntawm Aisi 321 Seamless Kub - deformed kav
Aug 15, 2025
Tso lus
AISI 321 Seamless Kub - deformed kav hlau yog ib qho kev ua tau zoo ntawm cov khoom lag luam thiab cov khoom ua haujlwm zoo tshaj plaws hauv qhov chaw siab. Cov txheej txheem deformation ntau ntxiv txhim kho cov yeeb nkab cov tshuab zog muaj zog thiab kev sib pauv khoom, ua kom sov, kev hloov cua sov, thiab siab}}}}}}}} {}}} Cov piping kub.
Qhov zoo ntawm Aisi 321 Seamless Kub - deformed kav
Zoo heev -} kub ua tau
Degiium nrog titanium (ti) ua tau zoo tiv thaiv cov tsis txaus siab (piv txwv li kub siab, ua rau kev xaiv hluav taws xob zoo nkauj rau kev hloov cua sov thiab kev tso pa tawm. Nws tuaj yeem ua haujlwm tsis tu ncua ntawm 900℃thiab intermittently nyob rau li ntawm 925 Degree, thiab nws cov kev ua tau zoo nyob rau hauv thermal cycling mob yog zoo dua li ntawm 304/316 stainless hlau.
Txhim kho corrosion tsis kam
Hauv cov acidic thiab chloride - Cov khoom ua pov thawj zoo rau oxidation, thiab kev nyuaj siab corrosion, thiab kev nyuaj siab corrosion cracking (SCC). Tshwj xeeb hauv kev siv uas muaj kev cuam tshuam txog sulfuric acid thiab nitric acid, nws ua tau zoo surpasses uas ntawm antm A312 cov qauv.
Seamless kub deformation lub zog
Ua ntawm kub extrusion thiab cool drasual, cov khoom siv ua kom zoo nkauj graph thiab boasts muaj qhov siab dua kev ntaus nqi piv rau welded kav. Nws cov cuab yeej ua haujlwm raug yog raws li hauv qab no: tensile lub zog ntau dua los yog sib npaug rau 205 MPa, thiab elongation ntau dua los yog sib luag rau 40%.

Dab tsi yog qhov sib txawv ntawm AISI 321 thiab 304 cov kav dej hlau stainless?
AISI 321 muaj titanium, uas tiv thaiv carbide nag lossis ntev {{1}- kev pabcuam kub piv rau 304.
Puas yog 321 kub {{- deformed seamless kav lub zog tshaj li txias tshaj li cas txias- drawn sawv?
Yog, 321 kub {{{- deformed kav thiab grain}} kub thiab siab {3} {} qhov kev pab siab.
Dab tsi cov qauv npog AISI 321 Seamless kub - deformed kav?
Cov qauv qauv suav nrog ASTM A312, Astm A269, En 10216-5, thiab Din 17456.
