Vim li cas Stainless Hlau Sib Nqus?
Teb: Cov neeg feem ntau siv cov hlau nplaum los kuaj xyuas cov hlau tsis zoo. Yog tias cov hlau nplaum tsis nyiam, nws yog qhov tseeb thiab ntawm tus nqi ncaj ncees. Ntawm qhov tsis sib xws, nws raug suav hais tias yog cuav. Qhov tseeb, qhov no yog ib qho tsis tshua muaj ib sab thiab tsis muaj tseeb ntawm kev txheeb xyuas qhov yuam kev.
Austenitic stainless hlau tsis muaj hlau nplaum los yog tsis muaj zog hlau nplaum; martensitic los yog ferritic stainless hlau yog hlau nplaum. Txawm li cas los xij, tom qab austenitic stainless hlau yog txias ua tiav, cov qauv ntawm cov txheej txheem yuav hloov mus rau martensite. Qhov ntau dua qhov ua deformation, ntau martensite transformation thiab ntau dua cov khoom sib nqus. Cov khoom siv yuav tsis hloov. Ib txoj hauv kev tshaj lij yuav tsum tau siv los txheeb xyuas cov khoom ntawm cov hlau tsis muaj steel. (Spectrum detection, stainless steel discriminating fluid detection).
