Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, A709 Gr 100 bridge steel plate based on a high starting point and high technology, the company has vigorously developed various steel products A709 Gr 100 bridge steel plate and deep-processed parts, steel structures, precision castings, seamless pipes.
ST52 steel angle steel with carbon content of 0.23% and yield point strength of 355 MPa is suitable for weldable and supporting members. In terms of chemical composition and mechanical properties, s355n is similar to A709 Gr 100 bridge steel plate en10025 - 3. Compared with ASTM A36, ST52 has higher strength and better welding performance. It is also used in daily life and industrial applications such as warehouses, equipment, etc. Note: although similar A709 Gr 100 bridge steel plate properties are shared, they are a little different. Please let us know your detailed requirements and we will tell you the most suitable steel grade.
Grades A709 Gr 100 bridge steel plate, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance. C, D, E grade steel has good low temperature toughness. Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts.
Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched A709 Gr 100 bridge steel plate increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of A709 Gr 100 bridge steel plate during tempering, while tempering determines the performance and life of the workpiece.
EN10025-6 S960QL structural steel plates are quenched and tempered high strength steel with yield strength of 590Mpa ~ 960MPa. A709 Gr 100 bridge steel plate, S960QL steel plates have technical requirement of flaw detection, Z15 Z35 thickness direction performance requirements, high strength and high toughness requirements and so on.
