Puas yog stainless hlau cov khoom sib nqus?

Feem ntau, austenitic stainless hlau tsis muaj hlau nplaum.Tab sis cov martensite thiab ferrite muaj hlau nplaum.Txawm li cas los xij, austenitic kuj tseem tuaj yeem sib nqus.Cov laj thawj yog raws li nram no:

Thaum solidified, ib feem hlau nplaum yuav tawm vim yog vim li cas smelting;coj 3-4 piv txwv li, 3 mus rau 8% residual yog ib qho tshwm sim, yog li lub austenite yuav tsum yog cov tsis muaj hlau nplaum lossis cov hlau nplaum tsis muaj zog.

Austenitic stainless hlau tsis yog hlau nplaum, tab sis thaum ib feem γ theem generates rau hauv martensite theem, hlau nplaum yuav tsim tom qab txias hardening.Kev kho cua sov tuaj yeem siv los tshem tawm cov qauv martensite no thiab rov ua kom nws tsis yog hlau nplaum.
