Tam sim no muaj peb yam tseem ceeb ntawm carbon steel cov ntaub ntawv rau siab qhov chaw ntawm boiler units nrog subcritical thiab saum toj no parameter theem: 20G, SA210A-1, thiab SA210C. Lawv yog siv los ua cua sov cov raj hauv qhov kub thiab txias superheaters, cov cua kub qis, cov phab ntsa dej txias, thiab cov khoom siv nyiaj txiag. Cov hlau tsim kub ntawm cov raj feem ntau yog 350 degree ~ 425 degree.
Txij li thaum cov ntsiab lus ntxiv ntawm carbon steel yog C thiab Mn, boiler manufacturers feem ntau nruj me ntsis txwv C cov ntsiab lus rau vuam kev ua tau zoo xav txog. Raws li cov lus piav qhia hauv ASME: Rau txhua txhua {{0}}.01% txo qis hauv cov ntsiab lus carbon hauv qab cov ntsiab lus siab tshaj plaws carbon, cov ntsiab lus manganese raug tso cai kom nce li 0.06% siab dua cov ntsiab lus siab tshaj plaws manganese, tab sis qhov siab tshaj plaws yuav tsum tsis pub tshaj 1.35%.
SA210A-1 yog qib steel hauv Asmeskas ASME SA210M. Qhov sib txawv tseem ceeb ntawm nws thiab 210C yog cov ntsiab lus C. Hais txog kev ua tau zoo, lub zog ntawm SA210C yog li 10% siab dua li ntawm SA210A-1. Nws qhov tsim tau tso cai rau kev ntxhov siab nyob rau hauv qhov ntsuas kub ntawm 350 degree ~ 425 degree yog 10% siab dua li ntawm SA210A-1, uas txhais tau hais tias nyob rau hauv tib yam kev ua haujlwm, phab ntsa thickness ntawm SA210C yeeb nkab tuaj yeem txo los ntawm 10. % piv nrog SA210A-1. Yog li ntawd, siv SA210C billet rau SA210A-1 txhais tau tias phab ntsa thickness margin tuaj yeem nce 10%.
