daim ntawv thov:
High -Tsev Kev Pabcuam:Tsim los rau ib puag ncig uas muaj kev kub ntxhov ntau, ua tsaug rau ntxiv Chromium (Cr) thiab Molybdenum (Mo).
Cov Khoom Siv Hluav Taws Xob & Boilers:Zoo tagnrho rau kev tsim cov hlab ntsha uas tuav cov kua dej los yog cov pa roj ntawm qhov kub siab.
Corrosion Resistance:Muab kev tiv thaiv zoo dua rau oxidation thiab corrosion piv rau cov qauv carbon steels hauv siab -temp chaw.
Kev lag luam:Dav siv nyob rau hauv Roj & Roj, Petrochemical, thiab lub zog tsim.
Cov cuab yeej tshwj xeeb:Fabricates Cheebtsam xws li kub exchangers, reactors, nruas, thiab lwm yam khoom siv tseem ceeb.
Qhov zoo:
High -Tsev Kev Pabcuam:Engineered los tswj lub zog thiab kev ncaj ncees nyob rau hauv siab kub systems xws li boilers thiab siab hlab ntsha.
Corrosion Resistance:Chromium cov ntsiab lus muab kev tiv thaiv zoo rau oxidation, aggressive media, thiab qaub kev pab cuam (H2S) tej yam kev mob.
Txhim kho lub zog:Molybdenum txhim khu lub zog tensile, tshwj xeeb tshaj yog nyob rau hauv high kub, thaum tuav zoo ductility thiab toughness.
Weldability:Lub alloy yog haum rau vuam, ib qho tseem ceeb feature rau fabricating complex khoom.
Versatility:Siv thoob plaws petrochemical, roj & roj, tshuaj, thiab fais fab kev lag luam rau ntau yam khoom.

1.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.
2.Dab tsi yog SA 387 12 cl1 khoom?
SA 387 Qib 12 Chav Kawm 1 yog chromium-molybdenum alloy steel phaj tsim los rau weldable boilers thiab siab hlab ntsha siv nyob rau hauv siab kub kev pab cuam, muab zoo corrosion kuj vim chromium thiab nce tensile lub zog ntawm kub kub los ntawm molybdenum, nrog rau chav kawm 1 qhia ib tug tshwj xeeb ntau yam rau tensile zog zog.
