ASTM A709-50W yog tus qauv kev tshwj xeeb rau cov qauv txheej txheem txheej txheem feem ntau hauv cov khoom sib txuas ntawm cov choj hlau. ASTM A709-50W npog lub zog siab, txo qis steel qauv qauv, phiaj hlau thiab tuav.

Cov tshuab hluav taws xob tsis kam ntawm cov hlau no nyob hauv feem ntau muaj cov pa hlau uas muaj ntau yam lossis tsis muaj tooj liab ntxiv. ASTM A709-50W yuav tsum muaj cov khoom siv tshuab hluav taws xob ntawm 6.00 lossis siab dua.

Lub chemistry ntawm aTM A709 Gr 66 Steel muag cov yeeb nkab tej zaum yuav muaj cov hauv qab no cov qog ua roj carbon, mangoron, phosphorus, thiab tooj liab hauv ib qho kev txwv.

Kev ntsuas xyuas nro xeem rau ntawm ASTM A709 Qib 50 Cov Yeeb Nkab Qib 50 tuaj yeem siv rau hluav taws xob tensile cov khoom. Feem ntau, tensile kev ntsuam xyuas cov tsis xws li tensile thiab paib muaj zog ntxiv rau kev ntxiv rau elongation cov yam ntxwv ib yam nkaus. Cov ntaub ntawv rau cov ASTM A709 Qib 50W Weather Cov Khaub Ncaws Steel Yeeb Nkab yog qhov yuav tsum tau ua raws li cov kev ntsuam xyuas hauv qab no.

Ua ntej, kev ntsuas cuam tshuam tau ua rau cov quav rau ob qho tib si tsis - bacture tseem ceeb nrog rau cov neeg sib cav tseem ceeb. Tom ntej no, cov quav ntawm Astm A709 yeeb nkab raug rau lub brinell hardness xeem rau qib 100 thiab 100W. Nws yuav tsum tau txheeb xyuas ASTM A709 qib 50W yeeb nkab rau atmospheric corrosion.
