SA 387 Gr 11 yog hais txog ASME SA-387 / ASTM A387 Qib 11 alloy steel phaj, chromium-molybdenum (Cr-Mo) steel tsim los rau kev kub siab hauv cov hlab ntsha siab, muab lub zog zoo heev, kev tiv thaiv corrosion (tshwj xeeb tshaj yog nyob rau hauv qaub roj), thiab siv lub zog tsim hluav taws xob, cov roj oxidation, feem ntau siv rau hauv cov roj av, roj thiab roj. Nws muaj kwv yees li 1-1.5% Chromium thiab 0.45-0.65% Molybdenum, nrog Class 1 thiab Class 2 variants qhia txog kev kho cua sov sib txawv rau kev txhim kho cov khoom.
SA 387 Gr 11 Chav Kawm 1hais txog ib hom kevChromium{0}}Molybdenum alloy steel phaj(ASTM A387), tsim los siv rau hauv weldedcov hlab ntsha siab thiab boilers ua haujlwm ntawm qhov kub siab, featuring txog1.25% Chromium thiab 0.5% Molybdenum.
SA 387 Gr 11 Chav Kawm 2yog ib qho chromium-molybdenum alloy steel phaj, teev los ntawm ASME (SA) thiab ASTM (A) cov qauv, tsim los rau kev pabcuam kub siab hauv cov hlab ntsha, boilers, thiab cov khoom siv hluav taws xob, muab lub zog zoo, oxidation tsis kam, thiab weldability.

Qhov txawv tseem ceeb: Chav Kawm 1 vs. Chav Kawm 2
Tib Chemistry:Ob chav kawm yog qhov tseem ceeb tib yam hlau alloy nrog cov ntsiab lus Cr-Mo.
Mechanical Properties:Qhov kev xaiv "Class" feem ntau hais txog cov khoom siv kho tshuab, nrog rau Chav Kawm 2 muaj zog tensile ntau dua thiab muaj zog dua li Chav Kawm 1, thaum Chav Kawm 1 muaj ntau dua elongation.
Cov ntawv thov siv
Roj & Roj:Cov hlab ntsha siab, cov kav dej, thiab cov khoom siv hauv refineries, tshwj xeeb tshaj yog rau cov kev pabcuam roj qaub vim muaj kev tiv thaiv corrosion.
Kev tsim hluav taws xob:Boilers, heat exchangers, thiab cov khoom ua haujlwm ntawm qhov kub thiab txias.
Kev ua tshuaj lom neeg:Cov khoom siv hauv cov nroj tsuag tshuaj uas muaj qhov kub siab tshaj plaws.
Yog tias koj muaj qhov yuav tsum tau ua rau SA 387 Gr 11 Chav Kawm 1 thiab SA 387 Gr 11 Chav Kawm 2, peb zoo siab tos txais koj cov lus 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.
