Q355NH material has a protective rust layer that resists atmospheric corrosion and can be used to manufacture low-alloy structural steels for steel structures such as vehicles, bridges, towers, containers, etc. It can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.
The company specializes in the research and development, production and sales of A709 Gr 50W carbon steel plate 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 A709 Gr 50W carbon steel plate five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,A709 Gr 50W carbon steel plate rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
Cold rolled A709 Gr 50W carbon steel plate steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner A709 Gr 50W carbon steel plate steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet
The steel such as A709 Gr 50W carbon steel plate delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.
There is a careful, patient, enthusiastic and thoughtful after-sales team, a professional distribution, ultra-efficient warehouse and logistics center, a marketing team with marketing expertise, an innovative technology center with strong steel technology, an experienced manufacturing center with rigorous professionalism Quality Inspection Center, an operation team with many years of administrative management experience. Such a strong combination of teams makes BEBON a steel giant in Henan Province.
