S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. A514 grade J 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. Tensile strength: 450-680MPa.
Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, A514 grade J alloy steel plate included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.
In 2019, through the concerted cooperation of the enterprise team, the sales volume has grown steadily, and the annual sales volume has exceeded 300 million yuan. For this reason, both the investors and employees of the enterprise have received satisfactory returns. With strong development potential and brand advantages, we have always been committed to "integrity, efficiency, pragmatism, dedication" corporate spirit, dedication to society, and return to the public. From this perspective, the enterprise will have a bright future. In a good environment with strong hardware facilities and excellent management personnel, we can make sure that the company will develop stronger and bigger.
Hot rolled A514 grade J alloy steel plate steel coil and plates are among our main products. Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the A514 grade J alloy steel plate processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, cracks are obviously healed, casting defects are reduced or eliminated, the as cast structure is transformed into deformed structure, and the processing properties of alloys are improved.
