Hlau yog ib qho alloy ua los ntawm ntau yam ntawm cov hlau -}}} ib txwm muaj hlau thiab carbon. Txawm li cas los xij, lwm cov ntsiab lus ntxiv rau cov ntaub sib txawv ntawm cov hlau sib txawv. Los ntawm carbon hlau mus rau steel hlau, ntau hom thiab pawg ntawm cov hlau muaj nyob. Qhov sib txawv hauv txhua hom steel nyob hauv nws cov tshuaj lom neeg muaj pes tsawg leeg.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm tus qauv qib 50 hlau
Piv txwv li, cov qauv qib 50 hlau, tseem hu ua Astm A572}}}}}}}}}}}}}, phosphorus, sulfur thiab silicon. Nws yog qhov siab - lub zog, cov hlau tsis muaj zog nrog lub zog tensile ntawm 65 ksi thiab tensile tawm los ntawm 50 ksi. Txheeb xyuas daim duab hauv qab no kom paub meej ntxiv.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau huab cua
Weathering hlau kuj tseem siab - muaj zog, qis}} {} {} {feem pua, uas tsim kom muaj freatility carbon ntau dua thiab weldability. Feem ntau cov cua hauv feem ntau muaj kev sib xyaw ua ke, phosphorus, leej faj, silicon, npib tsib, tooj thiab vanadium. Weather cov hlau muaj lub zog tensile ntawm 70 ksi thiab lub tensile tawm los ntawm 50 ksi.
Weathering hlau yog tsim los muab cov khoom siv tshuab txhim kho thiab tiv taus rau cov atmospheric corrosion. Thaum raug rau sab nraum zoov tej ntsiab, cov cuab yeej ua huab cua ib txwm muaj cov txheej txheem tiv thaiv patina, uas tsim los ntawm qhov tshwj xeeb faib khoom thiab kev pom zoo ntawm cov khoom siv hauv nws. Lub patina refenerates tsis tu ncua thaum raug huab cua kom tiv thaiv kev xeb tawm tsam corrosion.
Astm specifications rau cov hlau cua
Weathering hlau yog ib tsev neeg ntawm ASTM specifications thiab ntau cov cim specements tshwm sim zoo sib xws corrosion - cov khoom tiv thaiv. Lub ttm specifications muaj xws li A588, A242, A606- 4, A847, A871 {14 thiab A709-50W. Cov thawj cov khoom lag luam yog Cor-Tor®, uas yog Tebchaws Asmeskas Hlau Corporation (USS) Lub Npe Lag Luam rau cov khoom lag luam atmospheric resistant steel. Kev xaiv ntawm ib qho tshwj xeeb itm huab cua hlau specification yog nyob ntawm seb hom khoom xav tau. Piv txwv li, ASTM A588 npog cov qauv qauv, phaj, thiab bar thaum ATTM A242 npog steel phaj los ntawm ib nrab nti hauv tuab.
