Q345 is a steel material. It is a low alloy steel (C < 0.2%), with good comprehensive properties, low temperature properties, cold stamping properties, CCS grade A ferries steel welding properties and machinability. Q345 steel is subdivided into Q345A, Q345B, Q345C, Q345D and Q345E. This is the grade distinction, which represents that the impact temperature is different! Q345A, no impact; Q345B, impact at 20 degrees normal temperature; Q345C, impact at 0 degrees; Q345D, impact at - 20 degrees; Q345E, impact at - 40 degrees. At different impact temperature, the impact value is different.
12Cr1MoVR steel plate is suitable for medium and high temperature pressure vessels, and implements GB713-2014 standard. 12Cr1MoVR pressure vessel plate is usually delivered in normalizing + tempering state. According to the special agreement at the time of order, 12Cr1MoVR steel plate can also be delivered in annealing or tempering state, which significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.
The hot rolling method is to heat the CCS grade A ferries steel steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of CCS grade A ferries steel rolling process is usually called semi-finished product production, also called blank production.
As for the mechanical properties of CCS grade A ferries steel, ASTM A572 Gr.50, 345 Mpa is the yield point levels most closely approximating a geometric progression pattern between 36 ksi min yield point steels covered by Specification A36/A36M and 100ksi min yield point steels covered by Specification A514/A514M.
