How is the performance of S690QL steel

The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy S690QL steel products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of S690QL steel stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.

Medium and thick plates S690QL steel are mostly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction, etc. Medium and thick plates can also be used to make all kinds of containers, furnace shells, furnace plates, automobile static steel plates and so on. Among them, shipbuilding steel plate is used to make marine and inland ships. The shipbuilding steel plate S690QL steel is required to have high strength, plasticity, toughness, good cold bending performance, welding performance and corrosion resistance.

Corrosion resistant steel plate, as a new generation of advanced steel material, has 2-5 times of atmospheric corrosion resistance as ordinary carbon steel such as S690QL steel, and the longer the service time, the more prominent the corrosion resistance. Due to its characteristics of rust resistance, coating free, thinning and consumption reduction, labor saving and energy saving, corrosion resistant steel plate can be applied to steel structures exposed to the atmosphere for a long time, such as buildings, vehicles, bridges, towers, etc., and can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, etc.

With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of S690QL steel etc. steel material.

The toughness of steel such as S690QL steel is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.

There is a silo technology R&D center in our company with many experts. Our technical backbones go abroad to study advanced technologies regularly to make our technology and products leading in the world. We provide our customers with S690QL steel high-quality steel plates, the excellent quality from specialty. With good reputation, high-quality products, strong strength, and low prices, we welcome the clients from the world to come to visit our factory.

The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
