Alloy steel muaj ntau lwm yam tshaj li carbon steel
Alloy hlau txhais tau hais tias ntxiv rau silicon thiab manganese ua alloying cov ntsiab lus lossis deoxidizing cov ntsiab lus, cov hlau tseem muaj lwm cov ntsiab lus alloying (xws li chromium, nickel, molybdenum, vanadium, titanium, tooj liab, tungsten, aluminium, cobalt, niobium, zirconium thiab lwm yam. cov ntsiab lus) thiab lwm yam), thiab qee qhov kuj muaj qee yam tsis yog hlau (xws li boron, nitrogen, thiab lwm yam). Raws li cov ntsiab lus ntawm cov ntsiab lus alloying hauv cov hlau, nws tuaj yeem muab faib ua cov hlau tsis tshua muaj hlau, nruab nrab alloy steel thiab siab alloy steel.
Cov pa roj carbon steel feem ntau yog hais txog cov hlau uas nws cov khoom siv kho tshuab yog nyob ntawm cov ntsiab lus carbon hauv cov hlau, thiab feem ntau tsis ntxiv ntau cov ntsiab lus alloying, thiab qee zaum hu ua cov pa roj carbon steel lossis carbon hlau.
Carbon steel is also called carbon steel, an iron-carbon alloy with a carbon content of less than 2% WC. In addition to carbon, carbon steel generally contains a small amount of elements such as silicon, manganese, sulfur, and phosphorus. According to the application, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel. Carbon structural steel is divided into building structural steel and machine-made structural steel. According to the carbon content, carbon steel can be divided into low-carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%--0.6%) And high carbon steel (WC>0.6 feem pua ) Raws li cov ntsiab lus phosphorus thiab sulfur, carbon hlau tuaj yeem muab faib ua cov pa roj carbon zoo tib yam (siab dua phosphorus thiab sulfur), cov pa roj carbon zoo (qis phosphorus thiab sulfur) thiab qib siab- Cov hlau zoo (tsawg phosphorus thiab sulfur cov ntsiab lus) Feem ntau, qhov siab dua cov ntsiab lus ntawm cov pa roj carbon steel, qhov hardness thiab lub zog ntau dua, tab sis cov yas qis dua.
