The company covers an area of 15,000 square meters and the plant construction area is 10,000 square meters. We have introduced more than 50 sets of advanced A514 grade P alloy steel plate production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, A514 grade P alloy steel plate steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.
Smelting process of A514 grade P alloy steel plate, container plate SPA-H weather-resistant steel: The molten iron for smelting SPA-H steel must be pretreated by molten iron desulfurization. Before entering the converter, the sulfur content of the molten iron is ≤0.010%, and the slag on the surface of the molten iron is cleaned. Nickel plates, copper particles or nickel-copper alloys are added to the converter with scrap steel. The carbon content of the converter smelting end is required to be less than 0.06% to prevent the molten steel from being oxidized.
Pressure vessel plates A514 grade P alloy steel plate are used to manufacture pressure vessel equipment in petrochemical, gas separation and gas storage and transportation equipment. It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance. The general heat treatment of Q345R plate is hot rolling, controlled rolling, normalizing. The impact temperature is normal temperature, 0 ° C, -20.
At the initial stage of corrosion, the rust layer on the surface of weathering steel is denser than that of carbon steel, A514 grade P alloy steel plate, and there are relatively few cracks and holes. After 25 days, delamination occurs in some parts of carbon steel and weathering steel, and there is no difference in corrosion products, mainly due to the role of alloy elements in the rust layer. The precipitation of Cu and Cr alloy elements in the weathering rust layer can resist the invasion of moisture and harmful ions in the atmosphere, and further corrosion of steel and base metal can be prevented, so as to achieve the effect of atmospheric corrosion resistance.
S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. A514 grade P alloy steel plate, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.
Our company has its own steel plate manufacturing plant, processing plant and steel pipe plant.
