The effect of alloy elements on the properties of heat treatment methods for thick steel plate: the performance of heat treatment method reflects the difficulty coefficient level of heat treatment process and the tendency of defects caused by heat treatment process. The key points include cutting performance, over temperature sensitivity, quenching aging tendency and air oxidation carburizing tendency. A514 grade P tensile strength, carbon steel has high machinability, and slow cooling method can be used in heat treatment, which can reduce the deformation and cracking tendency of the products. The addition of Mn and Si will increase the over temperature sensitivity of steel.

What is the specific use of A514 grade P tensile strength, 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.

SM520B plate is Japanese standard low alloy high strength steel plate, which is in accordance with JIS g3101 standard. A514 grade P tensile strength, material SM520B is used for medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures bearing dynamic loads, mechanical parts, building structures, general metal structural parts. It is supplied in hot rolling or normalizing state, and can be used for various structures in cold areas above - 40℃.

The company attaches great importance to systematic management, and has passed the A514 grade P tensile strength ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on A514 grade P tensile strength quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.
