S420ML steel plates cutting into large diameter coil strip

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, S420ML steel plates 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.

What is the specific use of S420ML steel plates, hot rolled plate in daily life? First of all, hot rolled plate is used in bridge, vehicle structure, frame and other fields to play a role of bearing pressure. Secondly, high pressure boiler vessels are also made of hot rolled plates, which can be heat-resistant and airtight, and can stably seal the hot gas in the container. Thirdly, stainless steel hot rolled plate can be used to process hardware products. It has excellent corrosion resistance, and is easy for processing.

Difference between Q235A steel and Q235B steel plates: in the national standard GB700, the difference between S420ML steel plates, Q235A steel and Q235B steel plates is mainly in the carbon content. In addition, Q235A steel plate does not do impact test, while Q235B Q235B steel plates need normal temperature impact test, V-notch. Relatively speaking, the mechanical properties of Q235B steel plates are better than that of Q235A steel plate.

Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and S420ML steel plates resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, S420ML steel plates new materials, and promotes the competition of enterprises Struggle.
