KA36 ship structural steel plate heavy plate boiler steel

European standard high strength EN10025-6 S690QL steel plates are designed to provide excellent welding and bending properties. Due to its high strength, it enables design of lighter, more durable and efficient products and structures with S690QL steel plates and KA36 ship structural steel plate.The company specializes in the research and development, production and sales of KA36 ship structural steel plate seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has KA36 ship structural steel plate five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,KA36 ship structural steel plate rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the KA36 ship structural steel plate quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After KA36 ship structural steel plate quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.Alloy steel plate: The primary purpose of adding alloy elements to steel is to improve the hardenability of the steel, and it is easy to obtain martensite during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are smaller, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, KA36 ship structural steel plate.The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
