The EN 10025 S620Q high strength steel tensile strength from BBN

A514Gr.Q material is a quenched and tempered high-strength weldable steel plate under the ASTM standard. It is mainly used in places where high tensile strength and high yield are required, engineering vehicle lifting gears, and racks for offshore platforms. Depending on the thickness, its hardness is between 235-290, the yield is greater than 630MPa, and the tensile strength is greater than 700MPa.

Increasing the use of high-end steel will help reduce carbon emissions. The use of high-strength, high-toughness, corrosion-resistant and wear-resistant, fatigue-resistant, and long-life steel materials should be increased; on the basis of meeting the requirements for the use of steel products, the integrated application of structural lightweight design, lightweight materials, and lightweight manufacturing technologies should be realized; Improve the yield rate of steel and optimize the steel recycling system.

After heating, a billet is refined for several passes of rolling, then edge cutting and straightening to become a EN 10025 S620Q high strength steel steel plate, which is called hot rolling. Due to its high strength, good toughness, easy processing, good weldability and other excellent properties, hot rolled steel plate products are widely used in shipbuilding, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries.

Since the beginning of this year, the global EN 10025 S620Q high strength steel steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global EN 10025 S620Q high strength steel steel tube industry will also suffer from the "flash collapse" of international oil prices in March.
