The inventory status and trend of A387 gr 22 pressure vessel steel sheet

35CrMoA steel has high static strength, impact toughness and higher fatigue limit, higher hardenability than 40Cr, high creep strength and endurance strength at high temperature, long-term working temperature can reach 500℃; plasticity during cold deformation Medium, poor weldability. Alloy steel A387 gr 22 pressure vessel steel sheet is used as important structural parts that work under high loads, such as transmission parts of vehicles and engines; rotors, main shafts, heavy-load transmission shafts of steam turbine generators, and large-section parts.

The company is based on the principle of good faith, small profits and quick sales, and keeps forging ahead. In the fierce market competition, with A387 gr 22 pressure vessel steel sheet good cooperation and sincere service spirit, we win the trust of our customers and develop rapidly. We will create a win-win situation with our customers and create a better future with the belief of pioneering, pursuing excellence and learning.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the A387 gr 22 pressure vessel steel sheet steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the A387 gr 22 pressure vessel steel sheet weathering steel is purified and the content of inclusions is greatly reduced.

Compared with the common pressure vessel, the pressure parts of the boiler not only bear the pressure, but also suffer from the radiation and erosion of the high temperature flue gas. Once the pressure components of the boiler fail in operation, it will cause extremely serious consequences. Therefore, the A387 gr 22 pressure vessel steel sheet, steel materials used to manufacture the pressure components of the boiler must have enough high strength, plasticity, toughness, fatigue resistance and corrosion resistance, as well as good high-temperature mechanical properties for high-temperature components.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality A387 gr 22 pressure vessel steel sheet products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
