It is very important for an enterprise to have a sound after-sales service system, which not only ensures the normal outflow and inflow of the company's products, but also improves the trust of the company's products in the hearts of customers. Our company has a special after-sales service team and good after-sales service reputation. In case of any problem in the use of our steel products A514 grade E high strength steel plate , whether quality problem or not, the after-sales service department will assist in solving the problem as soon as possible, and regularly consult and track the use of the steel products.
Pressure vessel steel plate is mainly used for manufacturing pressure vessel or other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of A514 grade E high strength steel plate pressure vessel steel plate is 320kg / cm2 or 630kg / cm2 under normal pressure, and the temperature is within the range of - 20-450 ° C. It is required that the pressure vessel steel plate has not only certain strength and good plasticity and toughness, but also good cold bending and welding performance.
What is the difference between Q345B steel and Q345A steel? A514 grade E high strength steel plate, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.
Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The A514 grade E high strength steel plate metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other A514 grade E high strength steel plate alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary A514 grade E high strength steel plate carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.
