ls stainless hlau zoo dua Corten hlau

Stainless hlau tsis yog hnav-resistant li Corten steel, tab sis muaj cov hnav-resistant stainless hlau alloys rau kev cai daim ntaub ntawv. Stainless hlau kuj tseem muaj qhov sib txawv tsawg dua li huab cua hlau, tab sis qhov no yog qhov tseem ceeb.

Stainless hlau yog dab tsi?

Stainless hlau yog hlau uas muaj tsawg kawg yog 10.5% chromium thiab tsawg dua 1.2% carbon thiab lwm yam alloying ntsiab. Chromium oxidizes sai, tsim ib qho kev tiv thaiv lossis "passive" chromium oxide txheej ntawm cov hlau. Cov txheej oxide no ob leeg tiv thaiv corrosion thiab tiv thaiv cov pa oxygen nkag mus rau hauv cov txheej txheem ntawm cov hlau. Qhov ntau chromium uas ntxiv rau cov hlau muaj pes tsawg leeg, qhov ruaj khov ntawm oxide txheej yuav ua, yog li ua rau corrosion kuj.

Cor-Tensteel yog dab tsi?
Zoo ib yam li cov hlau tsis muaj steel, cov txiaj ntsig tseem ceeb ntawm huab cua hlau yog corrosion kuj. Thaum raug rau ntau yam atmospheric tej yam kev mob, weathering steel ib txwm tsim ib tug tiv thaiv txheej ntawm xeb hu ua patina. Thaum raug rau cov voj voog ntub thiab qhuav, cov txheej patina no yog regenerated tas li los tiv thaiv cov khoom no los ntawm corrosion yav tom ntej. Qhov tseem ceeb, weathering steel tsim cov txheej txheem tiv thaiv ntawm patina los ntawm xeb, thiab vim li ntawd, weathering steel muaj qis dua corrosion piv rau stainless hlau.
