Q370qC bridge steel plate performance and application
Q370qC is a bridge steel, which is widely used in riveted and bolt-welded highway bridges and railway bridges. Q represents the first letter of the Chinese pinyin of the word "yield" of the yield point of the bridge steel, 370 - the value of the yield point, Q - the first letter of the Chinese pinyin of the word "bridge" of the bridge steel; C—The quality level is C

Note:
(1): In order to improve the properties of steel, other trace alloying elements other than the above table can be added, and the data comes from the network and is for reference only.
(2): The allowable deviation of the chemical composition of the finished steel plate shall conform to the provisions
of GB/T222 Q370QC mechanical properties of the bridge plate: yield point:
δɡMPa 345-305. Tensile strength: δbMPa 510-490. Elongation δ5%: 21.
Q370qC bridge plate implementation standard:
1, Q370qC steel implementation standard GB/T714-2014.
2. Q370qC steel flaw detection implementation standard NB/T47013.3-2015 Q370q steel delivery status:
Q370q steel plate is usually hot-rolled, normalized, tempered, annealed and quenched
Q370Q steel plate is routinely used in bridge manufacturing and building structure construction. If you need Z-direction performance in the thickness direction, you can choose Z15/Z25/Z35 and other grades with Z-direction. Namely Q370qCZ15, Q370qCZ25, Q370qCZ35, Q370qDZ15, Q370qDZ25, Q370qDZ35, Q370qEZ15, Q370qEZ25, Q370qEZ35
