Analysis of fault layer problem of steel plate S690QL

With high-quality steel plate S690QL steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our steel plate S690QL steel market and improved the control of steel plate production quality.

P355NL1 steel plate is alloy special steel, steel for pressure equipment, with good plasticity, toughness, cold bending performance and welding performance. The steel is used to manufacture spherical storage tanks of more than 50 cubic meters, and can also be used to manufacture single-layer coil welding vessels, multi-layer hot-sleeve coil welding vessels, second and third category vessels and low-temperature pressure vessels.

The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, steel plate S690QL flat steel can be used as raw material for processing welded pipes. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Third, flat steel can be directly used as a steel structure. As a finished material, flat steel can be used for making hoop iron, tools and mechanical parts, and used as building frame structure and escalator in construction. Fourth, the flat steel has a smooth surface and a certain degree of beauty.

The wear-resistant plate has the main advantages of high strength and hardness, good toughness, steel plate S690QL high tensile strength, good material wear-resistance, long service life and low cost. In order to verify the wear-resistant life of the high wear-resistant composite steel plate applied in the field, the comparative industrial test of steel plate S690QL wear-resistant with the ordinary carbon plate was carried out on the reclaimer of Jigang raw material plant, and the effect is good.

Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with steel plate S690QL, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.

With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel steel plate S690QL product quality. Reaching every corner of the globe with professional services, users anywhere can get thoughtful and detailed services form us is our pursue. We promise all our steel materials are manufactured and tested in accordance with responding standards. We will take full responsibility for the quality of the steel materials we provide.
