Stainless hlau castings nrog sib nqus vim li cas thiab kev daws teeb meem.

Tom qab ua tiav ntawm kev tsim cov hlau stainless castings yog cov hlau nplaum yuav ua rau nws cov khoom tsis tsim nyog, yog li nyob rau hauv cov txheej txheem ntawm kev ua thiab zus tau tej cov stainless hlau castings yuav tsum tau them sai sai mus rau ib tug ntau ntawm cov ntsiab lus, kom tsis txhob txias molding ntawm stainless hlau castings nrog. magnetic, cov hauv qab no piav qhia txog cov laj thawj ntawm stainless hlau castings nrog hlau nplaum thiab kev daws teeb meem.

Raws li peb txhua tus paub, kev tsim cov hlau tsis muaj steel hlau ntawm austenitic stainless hlau yuav tsum tsis txhob sib nqus, tab sis qee yam ntawm cov khoom tsim tawm yog hlau nplaum, qee cov tuam txhab xav tias nws yog vim li cas rau cov khoom siv, tab sis tom qab kuaj spectral, cov khoom tsim nyog thiab tsis muaj qhov txawv txav, kom ntau tus neeg nrhiav tsis tau qhov teeb meem thiab daws tsis tau qhov teeb meem no. Tom qab kev sab laj nrog ntau cov ntaub ntawv thiab kev sib txuas lus nrog cov neeg ua haujlwm muaj feem cuam tshuam, peb tau pom tias yog vim li cas vim li cas cov hlau tsis muaj hlau tsis zoo yog hlau nplaum yog vim cov qauv sab hauv ntawm austenitic stainless hlau tau hloov pauv hauv cov txheej txheem ntawm kev ua kom txias thiab molding, qee qhov. austenite tau hloov mus rau martensite, thiab martensite ntawm lub cev nruab nrab qauv yog sib nqus. Yog li vim li cas cov qauv austenite hloov mus rau martensite qauv?

Stainless hlau raws li tus qauv tuaj yeem muab faib ua austenitic stainless hlau, martensitic stainless hlau, ferritic stainless hlau. Ntawm lawv, austenitic stainless hlau yog ib hom stainless hlau siv ******. Austenitic stainless hlau yog theoretically tsis-sib nqus, tab sis austenitic stainless hlau yuav tsim cov hlau nplaum tom qab ua haujlwm txias. Raws li qee qhov kev tshawb fawb hauv tsev thiab txawv teb chaws, Yog vim li cas vim li cas austenitic stainless hlau castings yog sib nqus yog tias thaum cov hlau tsis huv yog rhuab saum toj no austenitic hloov kub thaum lub sij hawm ua cov txheej txheem thiab khaws cia rau ib lub sij hawm, lub stainless hlau yuav hloov. rau hauv austenite, tab sis tom qab ntawd cov hlau tsis xeb hlau yuav tsum tau txias thiab tsim. Nyob rau hauv cov txheej txheem ceev ceev, thaum lub austenite txias mus rau martensite hloov kub, lub koom haum pib hloov mus rau hauv martensite. Qhov kev hloov pauv yuav tsis tso tseg kom txog thaum qhov kub thiab txias poob qis dua qhov hloov pauv kub los ua cov qauv martensitic. Nyob rau hauv zus tau tej cov stainless hlau castings, stability ntawm austenitic stainless hlau, tus nqi ntawm kev deformation, thiab cov txheej txheem yuav cuam tshuam nws transformation rau hauv martensitic stainless hlau.

Yog li, raws li cov laj thawj thiab cuam tshuam ntawm martensite, txhawm rau zam kev tsim cov hlau nplaum hlau tsis zoo, nws yog ib qho tsim nyog los xaiv austenitic stainless hlau nrog cov ntsiab lus siab ntawm austenitic ntsiab thaum yuav khoom raw. Nws kuj tseem siv tau los tshem tawm cov hlau nplaum thiab ua haujlwm nyuaj phenomena. * Muaj "alloy degaussing agent" nyob rau hauv kev ua lag luam uas tuaj yeem tshem tawm cov hlau nplaum ntawm stainless hlau castings, uas tuaj yeem hloov cov hlau hauv stainless hlau castings rau hauv austenite, thiaj li ua tiav lub hom phiaj ntawm degaussing, thiab tib lub sijhawm, Tom qab ntxiv cov alloy degaussing tus neeg sawv cev, qhov kev tiv thaiv corrosion thiab ntsev tshuaj ntsuam ntawm stainless hlau castings yog zoo.
