Txheej txheem cej luam ntawm cov yam ntxwv ntawm 321 stainless hlau kav

321 stainless hlau tubing yog titanium-stabilized austenitic alloy paub txog nws zoo heev -kub kev ua haujlwm, oxidation tsis kam mus txog 1500℃F (816 degree), thiab superior tsis kam rau sensitization (carbide nag lossis daus) thaum vuam. Yog li ntawd, nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv aerospace, kev ua tshuaj lom neeg, thiab cov khoom siv hluav taws xob. Nws muaj lub zog zoo, toughness, thiab corrosion kuj, outperforming hom 304 stainless hlau ntawm qhov kub thiab txias, tab sis nws tsis haum rau cov hniav polishing los yog corrosive acidic / alkaline ib puag ncig.

Dab tsi yog qhov specifications ntawm SS 321?

321 stainless hlau muaj qhov ceev ntawm 0.29 g / cm³. Nws elastic modulus yog 193 GPa. Qhov hluav taws xob tiv thaiv yog 72 microohm-cm. Lub thermal conductivity yog 16.1 W / mK ntawm 100℃thiab 22.2 W / mK ntawm 500 degree.

 

321 stainless hlau tubing yog titanium -stabilized alloy tsim rau siv nyob rau hauv kub txog li 900 degrees Celsius nyob rau hauv oxidizing atmospheres. Kev lag luam nrog cov kev cai nruj rau kev ua kom sov thiab kev ntseeg tau ntawm cov txheej txheem cia siab rau cov kev qhia tshwj xeeb ntawm 321 stainless hlau tubing. Vim nws lub zog muaj zog heev thiab muaj peev xwm tiv taus qhov kub thiab txias yam tsis muaj kev ua haujlwm degradation, 321 stainless hlau yog cov khoom siv ua haujlwm siab rau ntau cov kav dej hauv ntau qhov kev lag luam.

Mechanical Specification ntawm Stainless Hlau 321 Yeeb Nkab

Zoo heev Corrosion Resistance
Ib qho ntawm qhov zoo tshaj plaws ntawm 321 stainless hlau tubing yog nws zoo heev corrosion kuj. Qib no muaj 18% chromium thiab 8% npib tsib xee, zoo ib yam li lub qhov dej- paub qib 304, tab sis nrog kev sib ntxiv ntawm titanium. Lub titanium nyob rau hauv 321 stainless hlau stabilizes tus qauv, tiv thaiv kev tsim ntawm chromium carbides ntawm kub kub. Qhov no ua rau 321 stainless hlau tshwj xeeb resistant rau intergranular corrosion tom qab raug kub los ntawm 800℃F mus rau 1500℃F (427℃rau 816 degree).

Zoo heev High -Kev Ua Haujlwm Kub
321 stainless hlau muaj npe nrov rau nws lub peev xwm los tswj nws cov khoom ntawm qhov kub thiab txias. Nws tuaj yeem tiv taus qhov kub thiab txias mus txog 1500 ° F (816 ° C) thiab qhov kub thiab txias ntawm 1652 ° F (900 ° F). Qhov kev tiv thaiv tshav kub no yog los ntawm kev sib ntxiv ntawm titanium, uas tiv thaiv carbide nag lossis daus thaum vuam thiab siab - kub raug.

Jet engine Cheebtsam

Zoo Mechanical Properties
Ntxiv rau corrosion thiab kub tsis kam, 321 stainless hlau tubing kuj muaj cov khoom siv zoo. Nws nthuav tawm qhov sib npaug zoo ntawm lub zog, toughness, thiab ductility, ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau ua kom muaj zog thiab yoog raws. Cov khoom siv lub zog tensile thiab lub zog tawm los yog piv rau 304 stainless hlau, tab sis nrog kev ua tau zoo ntawm qhov kub thiab txias.
Daim ntawv thov:
Cov hlab ntsha siab
Kev lag luam roj thiab roj
Industrial kav dej

Weldability thiab Formability
321 stainless hlau tubing yog lub npe hu rau nws zoo heev weldability thiab formability. Qhov sib ntxiv ntawm titanium txo qhov kev pheej hmoo ntawm carbide nag lossis daus thaum lub sijhawm vuam, uas tuaj yeem ua rau rhiab heev thiab corrosion tom qab. Qhov no ua rau vuam thiab fabrication yooj yim dua yam tsis muaj kev cuam tshuam cov khoom siv. Tsis tas li ntawd, 321 stainless hlau yog yooj yim tsim thiab loj kom tau raws li ntau yam kev xav tau, ua rau nws haum rau ntau yam kev siv.
Daim ntawv thov:

Oxidation Resistance
Lwm cov yam ntxwv tseem ceeb ntawm 321 stainless hlau tubing yog nws cov oxidation tsis kam. Cov khoom no tiv taus oxidation txawm tias kub txog 1652℃F (900 degree), ua rau nws haum rau siab - kub daim ntawv thov uas yuav tsum tau tshwj xeeb oxidation kuj. Cov cuab yeej no ua kom ntseeg tau tias cov khoom siv tswj hwm nws cov qauv kev ncaj ncees thiab zoo li txawm nyob rau hauv cov xwm txheej hnyav.
Kev siv thaj chaw:
Muaj boilers
Tshuaj reactors
High -kub gaskets

Cov ntsiab lus:
321 stainless hlau tubing muab kev txhim khu kev qha thiab tus nqi - kev daws teeb meem zoo rau siab - kub, corrosive ib puag ncig qhov chaw ruaj khov thiab kav ntev yog qhov tseem ceeb. Nws muaj kev ua tau zoo dua piv rau tus qauv 304 stainless hlau.
