A387Gr91Cl2 pressure vessel plate is equivalent to the Chinese grade 10Cr9Mo1VNbN steel. normalized A131 grade E hull steel plate, A387Gr91Cl2 alloy steel plate not only has high oxidation resistance and high temperature steam corrosion resistance, but also has good impact toughness and high and stable durable plasticity and thermal strength performance. When the use temperature is lower than 620 ℃, its allowable stress is higher than that of austenitic stainless steel, normalized A131 grade E hull steel plate.
The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. normalized A131 grade E hull steel plate, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.
In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.
Our products have perfect after-sales system to protect the interests of customers. At the same time, we can according to normalized A131 grade E hull steel plate customer's requirements, processing requirements, cutting technical requirements, etc., to develop detailed solutions for customers, so as to make customers 100% satisfied.
