high quality of EN1522 FB5 class Heavy Plate Available

Low alloy steel plate was originally developed for large diameter oil and gas pipeline in 1960s. Pipeline steel materials used in oil and gas projects require higher strength and toughness than low carbon steel, and have good weldability just the same as low carbon steel.Advantages: high quality of EN1522 FB5 class, Low alloy steel plate has superior performance and light weight.Disadvantages: Low alloy steel plate is killed steel, so the price will be more expensive.

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of high quality of EN1522 FB5 class circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and high quality of EN1522 FB5 class management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

As the thickness and hardness of high quality of EN1522 FB5 class increase, the tendency to crack at the cutting edge increases. In order to prevent the high quality of EN1522 FB5 class from cutting cracks, preheating should be carried out before high quality of EN1522 FB5 class cutting. Special attention should be paid to preheating to make the entire high quality of EN1522 FB5 class interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole high quality of EN1522 FB5 class cannot be preheated, the partial preheating method can be used instead.

After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of high quality of EN1522 FB5 class, low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, high quality of EN1522 FB5 class sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
