ASME SA387 Gr.11 Cl.1yog ib qho tshwj xeeb chromium-molybdenum alloy steel phaj tsim rau qhov tseem ceeb siab -cov ntawv thov kub. Feem ntau tsim los rau fabrication ntawm welded boilers thiab siab hlab ntsha, cov khoom no leverages synergistic los ntawm nws cov ntsiab alloying tseem ceeb kom xa ib tug sib npaug ntawm kev ua tau zoo cwj pwm.

Daim ntawv thov
Cov Khoom Siv Hluav Taws Xob thiab Boilers
Nws yog cov khoom siv tseem ceeb rau kev tsim cov welded siab hlab ntsha thiab cov boilers uas ua haujlwm nyob rau hauv kev nce siab ntxiv - qhov kub thiab txias. Nws zoo heev thermal stability thiab creep kuj ua kom ntev - lub sij hawm structural kev ncaj ncees, txawm thaum raug rau cyclic cua sov thiab txias txheej txheem.
Kev lag luam roj thiab roj
Cov hlau yog dav siv nyob rau hauv cov dej ntws ntws, nruab nrab thiab qis kev ua haujlwm ntawm cov roj thiab roj. Nws yog qhov zoo tshaj plaws rau kev tsim cov cuab yeej tseem ceeb hauv refineries, petrochemical nroj tsuag thiab offshore drilling platforms, tshwj xeeb tshaj yog rau cov tshuab tuav qaub roj thiab siab -kub hydrocarbon kua, ua tsaug rau nws superior tiv thaiv sulfide kev nyuaj siab tawg thiab chloride corrosion.
Fais fab Tsim Sector
Nws ua lub luag haujlwm tseem ceeb hauv cov chaw tsim hluav taws xob thermal thiab ua ke - lub zog hluav taws xob. Cov khoom siv yog siv los tsim cov khoom tseem ceeb ntawm boiler systems, xws li superheater headers thiab reheater tubes, nrog rau cov cua sov rov qab lub tshuab hluav taws xob (HRSGs), qhov uas nws tiv taus siab - kub flue gases thiab superheated chav kom tswj tau lub zog hluav taws xob.
Tshuaj thiab Pharmaceutical Industries
Nws yog qhov kev xaiv zoo tshaj plaws rau fabricating reactors, tshav kub exchangers thiab cia tso tsheb hlau luam nyob rau hauv chemical processing nroj tsuag thiab chaw tsim tshuaj. Nws corrosion kuj tiv thaiv ntau yam acidic thiab alkaline xov xwm ua rau nws haum rau tuav cov txheej txheem nruj heev ntawm qhov kub siab.
Pulp thiab Ntawv, thiab Fertilizer Industries
Cov hlau phaj yog siv rau hauv kev tsim kho ntawm siab - cov khoom siv kub ua haujlwm hauv cov ntaub so ntswg thiab ntawv mills, nrog rau cov chiv tsim cov nroj tsuag, qhov uas nws tiv taus cov corrosive los ntawm cov tshuaj reagents thiab tswj kev ua tau zoo nyob rau hauv kev ua haujlwm hnyav.
Tag nrho cov specification thiab cov ntsiab lus muaj nyob rau ntawm kev thov. Cov ntaub ntawv saum toj no yog muab rau kev taw qhia nkaus xwb. Rau cov qauv tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.
Dab tsi yog qhov txawv ntawm SA 387 GR 11 cl1 thiab cl2?
Qhov txawv ntawm SA 387 Qib 11 Chav Kawm 1 thiab Chav Kawm 2 Phaj nyob hauv lawv cov khoom siv kho tshuab. Txawm li cas los xij, lawv ob leeg muaj tib yam tshuaj muaj pes tsawg leeg. Lub zog tensile thiab lub zog ntawm cov khoom siv hauv chav kawm 2 yog siab dua li ntawm chav kawm 1, qhov elongation rau chav kawm 1 yog siab dua piv rau chav kawm 2.
Dab tsi yog qhov kub thiab txias SA 387 GR 11?
Nyob rau hauv qis kawg ntawm qhov kub ntawm SA 387 Gr 11 (1150 ° F min tempering kub), thiab SA 387 Gr 22 (1250 ° F min tempering kub) yog siv. Cov qib no tuaj yeem teev nyob rau hauv chav kawm 1 lossis 2 thiab tseem tuaj yeem muab rau hauv Normalized & Tempered lossis Quenched thiab Tempered.
