Wholesale price of hardness of S690QL matrial

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, hardness of S690QL based on a high starting point and high technology, the company has vigorously developed various steel products hardness of S690QL and deep-processed parts, steel structures, precision castings, seamless pipes.

Mold steel plates are used to make various plastic molds, high mirror molds, mold bases, etc. Mould steel specifications range: thickness 8mm-650mm; width 1500mm-4020mm; length 3000mm-18000mm. According to performance and user needs, steel plates hardness of S690QL can be delivered in hot rolling, controlled rolling, normalizing, annealing, tempering, normalizing + tempering, quenching and tempering.

Wear resistant plate is composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal conditions, the thickness of the hardness of S690QL alloy wear-resistant layer of the wear-resistant plate is 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the hardness of S690QL wear-resistant property to meet the requirements of specific working conditions.

The related factors of hardness of S690QL steel plate cutting are mainly steel plate material, steel plate specific use and steel plate cutting requirements, so it can be said that there are many related factors. Different processing methods, such as finish machining and rough machining, choose different hardness of S690QL steel plate cutting methods. Wire cutting or plasma cutting is used for finishing and flame cutting is used for rough machining. Therefore, it can be concluded that the steel plate cutting methods selected under different processing methods are different.

How much is plate hardness of S690QL per ton?
FOB Shanghai: 635$/ton
q345qd steel is steel for highway bridges, which is a thick steel plate specially used for erecting railway lines or road and highway bridges. It is required to have high compressive strength, ductility and bearing the load and impact of railway vehicles, as well as excellent fatigue relief, certain ultra-low temperature ductility and air corrosion resistance.
