Weathering Steel nta

Hais txog cov hlau tsis tshua muaj hlau uas muaj cov txheej txheem tiv thaiv xeb uas tiv thaiv huab cua corrosion thiab tuaj yeem siv los tsim cov qauv hlau xws li tsheb, txuas hniav, yees, thiab ntim khoom. Piv nrog rau cov pa roj carbon zoo tib yam, cov huab cua steel muaj qhov zoo dua corrosion nyob rau hauv cov huab cua. Piv nrog rau cov hlau tsis muaj steel, cov hlau tsis muaj zog tsuas yog me me ntawm cov hlau alloying, xws li phosphorus, tooj liab, chromium, npib tsib xee, molybdenum, niobium, vanadium, titanium, thiab lwm yam. Tag nrho cov ntsiab lus ntawm alloying tsuas yog ob peb feem pua, tsis zoo li stainless. steel, uas ncav cuag 100%. Kaum ib xees, yog li tus nqi kuj tsawg
