Qhov kev qhia tshwj xeeb no suav nrog CARBON STEEL H BEAM A709 GR.50. Kev ntsuas cua sov yuav tsum tau siv los txiav txim qhov feem pua ntawm cov pa roj carbon, manganese, phosphorus, sulfur, silicon, thiab tooj liab rau cov tshuaj muaj pes tsawg leeg. Kev ntsuas nruj yuav tsum tau siv los txiav txim siab cov khoom tensile xav tau xws li lub zog tensile, lub zog tawm los, thiab elongation. Cov ntaub ntawv yuav tsum tau txais: (1) ib qho kev ntsuam xyuas cuam tshuam rau cov tswv cuab tseem ceeb tsis muaj pob txha thiab pob txha; thiab (2) Brinell hardness test rau Qib 100 thiab 100W. Atmospheric corrosion kuj yuav tsum tau txiav txim.

CARBON STEEL H BEAM A709 GR.50 yog lub koom haum thoob ntiaj teb uas muab cov qauv txheej txheem rau cov tuam txhab steel. ASTM International luam tawm cov ntaub ntawv tseem ceeb ntawm kev faib tawm, kev ntsuam xyuas thiab kev qhia tshwj xeeb ntawm hom hlau, thiab cov tuam txhab hlau siv cov ntaub ntawv no los txiav txim siab cov khoom siv, cov yam ntxwv, tshuaj, thiab cov khoom siv hlau ntawm lawv cov hlau.
CARBON STEEL H BEAM A709 GR.50 yog tus qauv siv hauv Tebchaws Meskas los txiav txim siab qib steel ntawm steel h-pile beams thiab steel wide flange beams.
