In grade Q345D, Q is the symbol for yield strength, 345 means Q345D steel can bear a minimum yield strength of 345MPa. Moreover, GB/T1591 Q345D steel is a kind of Carbon and Low-alloy High-strength Steel, and GB/T1591 Q345D Steel Plates find their broad application areas in Construction of Bridges, Highway Construction and Other Engineering construction.
345D low-alloy high-strength steel plates can be delivered in either normalized or Thermo mechanically rolled condition, 345D low-alloy high-strength steel plates benefits to high strength structures, on the other hand weight saving in the final structure due to plate thickness can be reduced, thus increased effective loads during use as well as cost saving in fabrication.
345D low-alloy high-strength steel plates we bebon offered for our guests:
345D low-alloy high-strength steel plates additional condition :
UT (Ultrasonic examination),AR(As Hot Rolled only),TMCP(Thermal Mechanical Control Processing),N(Normalized),Q+T(Quenched and Tempered),Z Direction Test(Z15,Z25,Z35) ,Charpy V-Notch Impact Test,HIC test, NDT ,PWHT( Simulated Post Weld Heat Treatment),NACE0175,The Third Party Test (Such as SGS Test), Coated or Shot Blasting and Painting.
