Export 10mm thickness A387 GR.22 CL.2 pressure vessel steel sheet

Based on the principle of win-win and mutual benefit, the company operates in good faith, strictly controls the quality, and provides perfect after-sales service, which has won unanimous praise. The success of the company is not only the A387 GR.22 CL.2 pressure vessel steel sheet hard work and wisdom of the company's employees, but also the deep love of the majority of consumers. It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the A387 GR.22 CL.2 pressure vessel steel sheet steel industry.

Our company supply low-alloy high-strength structural steel common grades below: Q345B / C / D / E, A572Grade 50 sheet, A572Gr.55 plate, A387 GR.22 CL.2 pressure vessel steel sheet, A514 Grade B material, A709 Grade 50 steel. The company can provide low alloy structural steel plate thickness range of 6 ~ 200mm. Our low-alloy high-strength steel is widely used in various types of engineering structures such as steel structure construction, construction machinery, mining machinery, heavy vehicles, bridges, pressure vessels.

The wear-resistant plate A387 GR.22 CL.2 pressure vessel steel sheet shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and A387 GR.22 CL.2 pressure vessel steel sheet hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.

Most common A387 GR.22 CL.2 pressure vessel steel sheet steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled A387 GR.22 CL.2 pressure vessel steel sheet steel plates.
