How to improve the quality of EN steel grade S690QL material

Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business EN steel grade S690QL material department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and EN steel grade S690QL material after-sales service department constitute the service customer network.

Grade DH36 ship steel plate is a high-strength ship plate. Shipbuilding steel generally refers to the steel used for hull structure. It refers to the steel used for manufacturing the hull structure produced in accordance with the requirements of the classification society construction codes. EN steel grade S690QL material, DH36 ship steel plate is often ordered, scheduled, and sold as special steel. We can supply various sizes and shapes of ship steel like plates , steel angles, bulb flat, steel channel and section steel.

The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the EN steel grade S690QL material and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.

Alloy steel means that alloy elements are specially added to improve the properties of steel. For example, nickel can improve the strength without reducing the toughness of steel; chromium can improve the hardness, corrosion resistance and wear resistance of high carbon steel. The properties of EN steel grade S690QL material, alloy steel depend not only on chemical composition, but also on proper heat treatment to a greater extent.

EN steel grade S690QL material, SA36 steel plate is one of our main product, it is belong to the carbon and low alloy high strength steel plate. We can supply the different sizes of SA36 steel plate. And the rolling size of SA36 steel plate is following: the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the SA36 steel coil thickness should not exceed 25 mm.
