Qhov txawv tseem ceeb:
Chav Kawm 1:Tsawg zog, zoo formability / weldability.
Chav Kawm 2:Lub zog ntau dua, kev ua tau zoo dua hauv kev xav tau siab dua - qhov kub thiab txias ib puag ncig.
Yog tias koj muaj qhov yuav tsum tau ua rau SA 387 Gr 22 Chav Kawm 1 thiab SA 387 Gr 22 Chav Kawm 2, peb zoo siab tos txais koj qhov kev nug. GNEE tuav cov khoom lag luam loj uas feem ntau siv cov qib siab zog steel rau koj xaiv.Rau cov ncauj lus kom ntxaws txhua yam khoom, tshuaj lom neeg muaj pes tsawg leeg, thiab cov ntaub ntawv kev, nrog rau cov qauv dawb, thov hu rau peb lub Hoobkas tam sim ntawd.

1.Dab tsi yog SA 387 GR 22 khoom?
Lub SA 387 Qib 22 Steel yog lub nkoj siab steel ua los ntawm cov khoom siv raw khoom zoo thiab cov cuab yeej siv siab. Feem ntau siv rau kev ua haujlwm siab - qhov kub thiab txias raws li nws lub siab ua haujlwm siab, lub phaj hlau no tuaj yeem raug mus txog 600℃thaum tuav cov oxidation zoo thiab corrosion kuj.
2.Dab tsi yog ASTM A387 Qib 22 sib npaug?
Ntawm cov ASTM A387 Qib 22 sib npaug steel qib, SA387 Qib 22, 10CrMo9-10 yog nrov dua li lwm yam sib npaug. SA387 Qib 22 steel yog raws li ASME SA387 / SA387M tus qauv. Kev ua haujlwm tshuaj lom neeg thiab kev ua haujlwm ntawm SA387 Qib 22 steel yuav luag zoo ib yam nrog ASTM A387 Qib 22 steel.
3.Yog SA 387 carbon steel?
Weldable carbon steel daim hlau rau cov hlab ntsha siab thiab boilers siv nyob rau hauv siab kub. Cov khoom siv tau txais txiaj ntsig los ntawm kev ntxiv chromium thiab molybdenum uas muab cov hlau ntau dua corrosion tsis kam thiab tiv taus cua sov.
