At the same time of doing well in A514 grade E alloy steel plate production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the A514 grade E alloy steel plate technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
BBN provides a wide range of A514 grade E alloy steel plate ASTM A387 steel plates for pressure vessel manufacturers and the oil and gas industry. If you are interested in ASTM A387 steel plates or other A514 grade E alloy steel plate pressure vessel steels, please contact us for the latest prices.
A514 grade E alloy steel plate and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of A514 grade E alloy steel plate and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.
A514 grade E alloy steel plate, Q345B low alloy steel plate composition: 1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%; 2) Add manganese-based alloying elements; 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel; In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.
S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. A514 grade E alloy steel plate, S355J2+N low alloy steel plate is widely used in bridges, vehicles, ships, building steel structures. Mechanical properties of S355J2+N steel: Yield strength: ≤16mm: ≥355; 16-40: ≥345; 40-63: ≥335; 63-80: ≥325;80-100: ≥315; 100-150: 295; 150-200: ≥285; 200-250: ≥275; 250-400: ≥265.
