Hot rolled EN 10025 S550QL high strength steel welding property

Low alloy steel plate, refers to the steel plate whose alloy content is less than 3.5%. The most popular low alloy steel plate is EN 10025 S550QL high strength steel, Q345B plate and its equivalent materials such as S355JR, A572 grade 50 and so on. Low alloy steel plate plays an important role in the construction, it must have enough strength and stability to bear the safety of the house. Low alloy steel plate is often used in large buildings with large bearing capacity and good cross-section stability, such as bridges, ships, lifting and transportation machinery, etc.

Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from EN 10025 S550QL high strength steel. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.

Machining of EN 10025 S550QL high strength steel, wear resistant steel plate: wear resistant steel plate has good cutting and shearing properties. During machining, the cutting tools and feeding speed should be used reasonably according to the hardness of steel plate. Common tools are made of high speed steel or cemented carbide steel, and carbide surface tools are required for grinding. Wear resistant steel plate can be welded to structural steel by arc welding.
