Carbon steel high strength steel plate S690QL angles

high strength steel plate S690QL and so on medium and heavy plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on fields. The surface quality problems of medium and heavy plates not only affect the appearance of the products, but also reduce the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate. Therefore, the medium and heavy plates manufacturers and users attach great importance to it. The surface quality of medium and heavy plate mainly refers to the surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plates.

The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in high strength steel plate S690QL etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.

During the steel plate cutting, the special-shaped steel plate cutting process is often carried out. In this operation process, some cutting curves will be generated. Therefore, there should be relatively high precision standards during the processing of high strength steel plate S690QL. The operators need to have rich experience, and they also need to be proficient in the operation methods and working skills of the equipment, so as to ensure that the steel plate can meet the shape requirements after processing.

The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel. It can provide customers with drawing design, high strength steel plate S690QL deep processing services and installation solutions. 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world. The company has won widespread praise from customers.
