A 209 Khoom Specification
ASTM A209 Qib T1b alloy steel seamless yeeb nkab muaj ib tug raug chemistry nrog 0.44-0.65 Molybdenum ntxiv. Cov kabmob yam tsawg kawg nkaus tensile lub zog yog 415 Mpa Yam tsawg kawg nkaus lub zog ntawm ASTM A209 Qib T1b yeeb nkab yog 220 Mpa.
Scope
1.1 Qhov specification2 no suav nrog ntau qib ntawm qhov tsawg kawg nkaus-phab ntsa-thickness, seamless, carbon-molybdenum alloy-steel, boiler thiab superheater raj.
1.2 Qhov kev qhia tshwj xeeb no suav nrog cov raj 1/2 txog 5 nyob rau hauv. [12.7 txog 127 mm] suav nrog, sab nraud txoj kab uas hla thiab 0. ], suav nrog, hauv qhov tsawg kawg nkaus phab ntsa thickness.
1.3 Ib qho kev xaiv ntxiv uas yuav tsum tau muaj thiab, thaum xav tau, yuav tsum tau hais nyob rau hauv qhov kev txiav txim.
1.4 Cov txiaj ntsig tau teev nyob rau hauv ib nti-phaus units lossis SI units yuav tsum raug suav tias yog tus qauv. Nyob rau hauv cov ntawv nyeem, SI units tau qhia nyob rau hauv brackets. Cov nqi teev nyob rau hauv txhua qhov system tsis yog qhov sib npaug; Yog li ntawd, txhua qhov system yuav tsum tau siv nws tus kheej ntawm lwm tus. Kev sib xyaw cov txiaj ntsig los ntawm ob lub tshuab tuaj yeem ua rau tsis ua raws li qhov tshwj xeeb. Cov inch-phaus units yuav tsum siv tshwj tsis yog lub npe "M" ntawm qhov kev qhia tshwj xeeb no tau teev tseg hauv qhov kev txiav txim.
1.5 Cov txheej txheem thoob ntiaj teb no tau tsim los ua raws li cov txheej txheem thoob ntiaj teb lees paub txog kev tsim qauv tsim hauv Kev Txiav Txim Siab ntawm Cov Ntsiab Cai rau Kev Txhim Kho Cov Txheej Txheem Thoob Ntiaj Teb, Cov Lus Qhia thiab Cov Lus Pom Zoo los ntawm World Trade Organization Technical Barriers to Trade (TBT) Committee.
