Raws li ib txwm muaj, tsuas muaj ob hom steel phaj, tiaj tus lossis duab plaub.Rolled lossis dav hlau strips tuaj yeem txiav los ua cov ntawv hlau tshiab.Muaj ntau hom steel phaj.Yog hais tias lawv muab faib raws li thickness ntawm steel phaj, yuav muaj thickness.Cov hlau nyias nyias tuaj yeem muab cais ntxiv.Cov hom muaj xws li cov hlau zoo tib yam, lub caij nplooj ntoos hlav steel, hlau alloy, cov hlau tsis muaj cua sov, cov phom-pov thawj daim hlau, cov yas puas steel phaj, thiab lwm yam.

Alloy steel yog tsim los ntawm kev ntxiv cov ntsiab lus alloying rau cov ntaub ntawv hlau.Hauv cov txheej txheem no, cov ntsiab lus tseem ceeb hauv cov hlau, uas yog hlau thiab carbon, yuav muaj qee yam cuam tshuam nrog cov ntsiab lus tshiab ntxiv alloying.Raws li cov txiaj ntsig zoo li no, cov qauv ntawm cov hlau Thiab cov khoom yuav muaj kev hloov pauv, thiab tag nrho cov kev ua tau zoo thiab zoo ntawm cov hlau tseem yuav raug txhim kho nyob rau lub sijhawm no.Yog li ntawd, cov zis ntawm cov hlau alloy tau txais loj dua thiab loj dua, thiab daim ntawv thov ntau dua thiab dav dua.

Muaj ntau hom hlau alloy, uas tuaj yeem muab faib ua ntau hom raws li cov qauv sib txawv.Yog tias muab faib raws li cov ntsiab lus muaj nyob hauv cov hlau, nws tuaj yeem muab faib ua peb pawg: cov hlau tsis tshua muaj hlau tsis muaj cov ntsiab lus carbon tsawg, tsawg dua 5%, thiab nruab nrab cov ntsiab lus carbon tag nrho, xws li 5% mus rau 10% Cov hlau nruab nrab. , siab tshaj carbon cov ntsiab lus, siab tshaj 10% siab alloy steel.Lawv cov qauv sib txawv, yog li qhov kev ua tau zoo yuav txawv, tab sis txhua tus muaj nws qhov zoo thiab yuav siv rau hauv ntau qhov chaw.

Yog hais tias muab faib raws li cov khoom muaj pes tsawg leeg ntawm cov hlau, nws tuaj yeem muab faib ua plaub hom: thawj yog chromium steel, uas chromium yog ib qho tseem ceeb ntawm alloying ntsiab.Hom thib ob yog chromium-nickel steel, qhov thib peb yog manganese steel, thiab hom kawg yog silico-manganese steel.Cov hom ntawm cov hlau alloy no muaj npe raws li cov ntsiab lus ntawm cov hlau alloying muaj nyob hauv cov hlau, yog li koj tuaj yeem nkag siab txog lawv cov ntsiab lus raws li lawv cov npe.

Kev faib tshwj xeeb kuj yog raws li lawv siv.Thawj hom alloy structural steel yog siv los ua ntau yam tshuab thiab engineering Cheebtsam.Cov hlau no tsuas muaj txoj cai hardenability, yog li muaj ntau yam siv Manufacturing qhov chaw ntawm cov twj paj nruag nrog rau cov cheeb tsam loj loj.Qhov thib ob yog cov cuab yeej hlau alloy.Raws li tuaj yeem pom los ntawm lub npe, cov hlau no feem ntau yog siv los ua qee yam cuab yeej, xws li cov cuab yeej ntsuas, cov pwm kub thiab txias, riam, thiab lwm yam. Cov hlau no muaj qhov hnav tsis kam thiab toughness..Hom thib peb yog cov hlau ua haujlwm tshwj xeeb, yog li cov khoom tsim muaj cov khoom tshwj xeeb, xws li cov hlau tsis muaj cua sov thiab hnav-resistant steel, uas tuaj yeem ua tau raws li qee qhov tshwj xeeb hauv kev tsim khoom.
