Austenitic stainless hlau yog cov hlau tsis muaj hlau nplaum lossis tsis muaj zog sib nqus, thaum austenitic-ferritic duplex stainless hlau yog hlau nplaum. 304 stainless hlau phaj yog austenitic stainless hlau, tab sis vim li cas nws thiaj li muaj me me ntawm martensite lossis ferrite?
Thaum lub sij hawm smelting los yog forging, kev kho cua sov tsis zoo los yog kev sib cais sib cais tuaj yeem ua rau muaj qhov me me ntawm martensite lossis ferrite hauv 304 stainless hlau phaj. Yog li ntawd, 304 stainless hlau phaj yuav muaj qhov tsis muaj zog hlau nplaum. Tsis tas li ntawd, cov qauv ntawm 304 stainless hlau phaj tuaj yeem hloov mus rau martensitic stainless hlau tom qab ua haujlwm txias. Qhov ntau dua qhov txias deformation, ntau martensite tsim, thiab ntau dua cov khoom sib nqus ntawm 304 stainless hlau phaj.
Piv txwv li, Ameslikas tsis-sib nqus 304 stainless hlau phaj tuaj yeem pom cov hlau nplaum tom qab txias txias thaum lub sij hawm tsim khoom ntawm lub dab dej, thiab cov hlau nplaum no tshwj xeeb tshaj yog nyob rau hauv kaum qhov chaw uas qhov deformation yog qhov loj tshaj. Txhawm rau tshem tawm tag nrho cov hlau nplaum ntawm 304 stainless hlau phaj tshwm sim los ntawm cov laj thawj saum toj no, kev kho kub kub tuaj yeem siv los kho cov qauv austenitic, hloov cov martensite lossis ferrite rau hauv austenite thiab tshem tawm cov hlau nplaum.
Nws yuav tsum raug sau tseg tias cov hlau nplaum ntawm 304 stainless hlau kav los ntawm cov laj thawj saum toj no yog qhov tshwm sim ib txwm muaj.
