How much is S690QL material cost per square foot

SM490B steel, S690QL material is a kind of low carbon welded structural steel. With this low carbon equivalent, it can produce good cold forming properties. SM490B steel plate is usually supplied in hot rolling or controlled rolling delivery conditions. The SM490B is commonly used in the engineering and construction industries. It has high yield and tensile strength, and provides a variety of processing and testing options to make it highly available in your construction projects.

Our company specializes in the production of steel plates, steel coil, steel sections, welded pipes and seamless pipes products, sales of GB, ASME, ASTM, JIS, DIN, EN, API and other standards and specifications of steel S690QL material and deep-processed products, facing the domestic and foreign markets, welcome to call for inquiries. It is a modern high-tech professional enterprise integrating scientific research, production and sales.

As the thickness and hardness of S690QL material increase, the tendency to crack at the cutting edge increases. In order to prevent the S690QL material from cutting cracks, preheating should be carried out before S690QL material cutting. Special attention should be paid to preheating to make the entire S690QL material interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole S690QL material cannot be preheated, the partial preheating method can be used instead.

Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, S690QL material included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel S690QL material products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
