A709 GR.50 CARBON STEEL H BEAM yog Cov Qauv Qhia Tshwj Xeeb rau Cov Hlau Hlau rau Cov Txuas Txuas thiab suav nrog cov pa roj carbon, lub zog siab qis-alloy, thiab quenched thiab tempered alloy steels siv los ua cov phiaj xwm hauv kev tsim cov choj. SSAB muaj tsib qib nram qab no ntawm A709; 36, 50, 50W, HPS 50W thiab HPS 70W. Peb qib huab cua ntawm 50W, HPS 50W, thiab HPS 70W muaj ASTM G101 txhim kho Atmospheric Corrosion Resistance Index ntawm Ntau dua lossis sib npaug rau 6.0.

Lub zog muaj zog, qis-alloy steel phaj siv feem ntau hauv kev tsim cov choj. Chapel Steel stocks A709 Qib 36, A709 Qib 50 thiab A709 Qib 50W. Cov qhab nia no feem ntau teev nrog Charpy cov kev xeem xa mus rau thaj chaw tshwj xeeb lossis qhov ntsuas kub qis tshaj qhov kev pabcuam. Cov kev ntsuam xyuas Charpy tau teev tseg tias tsis yog qhov tseem ceeb, uas yog ib qho kev ntsuas kub ib ntus (frequency "H"), lossis kev puas tsuaj tseem ceeb, uas yog ib qho kev sim ib-phaj (Frequency "P"). Choj hlau tseem tuaj yeem raug txiav txim rau ASSHTO M270 Specification hais txog AASHTO M270 Qib 36, AASHTO M270 Qib 50, AASHTO M270 Qib 50W.
