What is the strongest S690QL carbon steel plate sheet?

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel S690QL carbon steel plate sheet products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the S690QL carbon steel plate sheet market and has strong competitiveness.

SA387 Gr.12 Cl.2 steel data is suitable for the essence and gas treatment in hydrogenation reaction and conversion equipment at high temperature. It is a chrome molybdenum carbon alloy steel for use in weldable pressure vessels and industrial boilers. The maximum thickness of the steel plate can reach 250mm. According to different S690QL carbon steel plate sheet thickness and impact requirements, the delivery situation of SA387 Gr.12cl.2 steel plate is: normalizing and tempering or normalizing and rapid cooling and tempering.

Low-alloy high-strength steel grades are designed to have quite good notch toughness for their intended structural use. The applicability of the notch toughness of specific grades of low-alloy high-strength steel is either based on existing use experience or combined with the results of the impact test of notched specimens. In order to meet the very strict requirements of certain applications, some S690QL carbon steel plate sheet, low-alloy high-strength steels produced have excellent notch toughness. For example, controlled hot rolling technology is usually used to produce low-alloy high-strength steel plates for the manufacture of welded line pipes. Such steel pipes need to meet the requirements of relevant standards for notch toughness.

Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for S690QL carbon steel plate sheet and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.

EN10025-6 S960QL structural steel plates are quenched and tempered high strength steel with yield strength of 590Mpa ~ 960MPa. S690QL carbon steel plate sheet, S960QL steel plates have technical requirement of flaw detection, Z15 Z35 thickness direction performance requirements, high strength and high toughness requirements and so on.
