Industrial siv ntawmstainless hlauRaws li lub koom haum metallographic tuaj yeem muab faib ua peb pawg: ferritic stainless hlau, martensitic stainless hlau, austenitic stainless hlau. Nws tuaj yeem yog cov yam ntxwv ntawm peb hom stainless hlau no (raws li qhia hauv cov lus hauv qab no), tab sis nws yuav tsum tau muab sau tseg tias martensitic stainless hlau tsis yog txhua yam tsis tuaj yeem welded, tab sis tsuas yog los ntawm qee yam kev mob, xws li vuam yuav tsum. preheated tom qab welding yuav tsum kub kub kom cov txheej txheem vuam yog complex. Qhov tseeb ntau lawm ntawm ib co martensitic stainless hlau xws li 1Cr13, 2Cr13 thiab 2Cr13 thiab 45 steel vuam los yog ntau tshaj.

Ferritic stainless hlau kuj belongs rau chrome stainless hlau
Tsawg carbon cov ntsiab lus, tiv thaiv atmospheric, nitric acid thiab saline kua corrosion muaj peev xwm, kub oxidation kuj thiab lwm yam. Feem ntau yog siv los tsim cov khoom siv tshuaj hauv lub thawv, cov yeeb nkab.

Austenitic stainless hlau yog chrome nickel stainless hlau
Nws muaj lub siab corrosion kuj, zoo heev plasticity, zoo weldability thiab tsis kub toughness, tsis muaj hlau nplaum, yooj yim rau ua hauj lwm hardening. Feem ntau yog siv hauv corrosive media ua haujlwm hauv qhov chaw, ntim, kav dej, khoom siv kho mob thiab ib puag ncig tiv thaiv kev sib nqus.
