ASTM A709 Steel Phaj

Ib qho siab-ua kom muaj zog, qis-ntau cov qauv txheej txheem steel phaj siv dav siv hauv kev tsim khoom siv ua choj. Chapel Steel muaj nqis A709 Qib 36, A709 Qeb 50 thiab A709 Qeb 50W. Cov qhab nia feem ntau tau teev tseg nrog kev ntsuam xyuas Charpy hais txog thaj chaw tshwj xeeb lossis qis tshaj qhov ntsuas kev xav tau. Cov Kev Ntsuas Hluav Taws Xob tau txheeb raws li tsis tseem ceeb, uas yog qhov kev ntsuas kub ib zaug (zaus" H"), lossis thim qhov tseem ceeb, uas yog qhov kev xeem ib-phaj (Zaus" P") Cov. Choj cov hlau thaiv kuj tuaj yeem hais tau rau ASSHTO M270 Specification uas tau txheeb raws li AASHTO M270 Qib 36, AASHTO M270 Qeb 50, AASHTO M270 Qeb 50W.
