The company specializes in the research and development, production and sales of A131 EH40 ship 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 A131 EH40 ship steel plate five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,A131 EH40 ship 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.
High toughness and low brittleness transition temperature: with the increase of the working pressure of the A131 EH40 ship steel plate gas pipeline, the pipe diameter becomes larger, and the pipeline fracture accidents often occur. Toughness is the key factor affecting pipeline fracture. In order to ensure A131 EH40 ship steel plate pipeline safety, toughness and strength must be improved at the same time.
Steel can be divided into ordinary steel and special steel, which is an important symbol of a country's steel production level. The special steel includes spring steel, round steel, die steel, heat-resistant steel, wear-resistant steel, bearing steel and so on. Compared with ordinary steel, the A131 EH40 ship steel plate special steel has better physical properties, higher strength, stronger compressive strength and better accuracy. At the same time, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance.
Generally speaking, the higher the strength of A131 EH40 ship steel plate, weathering steel, the greater the hardness, while the plasticity and toughness will decrease. When the carbon content of weathering steel exceeds 1.2%, the hardness will increase, but the strength will not increase, but will decrease. Resilience will also decline quickly. When the carbon content is high, the cementite increases and forms network distribution, which weakens the connection between grains and makes the mechanical properties of steel worse.
GB standard wear resistant steel plates parameters: The standard for Chinese wear plates is GB/T 24186, which includes NM400, NM450, NM500, NM550, NM600 etc. steel grades. According to the standard, the NM400 plate thickness is no more than 80mm, and hardness is 370-430HBW. A131 EH40 ship steel plate, NM450 plate thickness is no more than 80mm, and hardness is 420-480HBW. NM500 plate thickness is no more than 70mm, and hardness is 470HBW min. And NM600 plate thickness is no more than 60mm, and hardness is 570HBW min.
