Technical key points of EN1522 FB7 steel for helmet production

Delivery status: Hot-rolled EN1522 FB7 steel for helmet steel In the hot-rolled state or controlled rolling state or heat treatment, the state of delivery, cold-rolled steel to the annealing state of delivery.

The company specializes in the research and development, production and sales of EN1522 FB7 steel for helmet seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has EN1522 FB7 steel for helmet five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,EN1522 FB7 steel for helmet rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to EN1522 FB7 steel for helmet full material. Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality. In early 2008, the company established the Ministry of foreign trade, and our EN1522 FB7 steel for helmet steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.

The main function of boron in EN1522 FB7 steel for helmet and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.

Our company will accept the product quality objection registration record, pass it to the EN1522 FB7 steel for helmet production unit and relevant departments, and timely coordinate the supervision of product EN1522 FB7 steel for helmet quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
