Steel Q345R (HIC) is a Q345R pressure vessel plate with hydrogen induced cracking resistance test. Q345R(R-HIC) plate is based on Q345R (HIC) and SSCC test, namely sulfide stress corrosion test. The delivery status of Q345R (HIC) and Q345R Q345R(R-HIC) plate is normalizing, - 30 ℃ impact, level I flaw detection, process reference standard GB713-2014. Steel A514 Gr B Plate, Q345R (HIC) and Q345R (R-HIC) plates are smelted by electric furnace + refining outside the furnace. The smelting process is Ca-treated, and should be intrinsically fine-grained steel. The actual grain size is 5 or above.Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional Steel A514 Gr B Plate production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of Steel A514 Gr B Plate leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.The hot rolling method is to heat the Steel A514 Gr B Plate 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 Steel A514 Gr B Plate rolling process is usually called semi-finished product production, also called blank production.Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as Steel A514 Gr B Plate. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.The company's after-sales service team is a high-quality professional team. Most after-sales employees have rich service experience and have reached the level of after-sales engineer. The after-sales department implements the after-sales personnel responsibility system and a 24-hour response mechanism. The company's advanced customer relationship management system provides customers with "standardized and streamlined services". A sound customer relationship maintenance system, and a "one-stop" customer satisfaction tracking system, all reflect our strong after-sales service guarantee.
