SA709 grade 50W carbon steel material for boilers and pressure vessels

SA709 grade 50W carbon steel material,The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the market and has strong competitiveness.

,SA709 grade 50W carbon steel material. and so on medium and heavy plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on fields The surface quality problems of medium and heavy plates not only affect the appearance of the products, but also reduce the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate Therefore, the medium and heavy plates manufacturers and users attach great importance to it The surface quality of medium and heavy plate mainly refers to the surface smoothness, surface defects, etc, which is one of the main quality indexes of medium and heavy plates,SA709 grade 50W carbon steel material.

304 stainless steel plate products have strong corrosion resistance. For ordinary alkali solution and organic acid, inorganic acid has good corrosion resistance. This material SA709 grade 50W carbon steel material is a high alloy steel, which can resist corrosion in air or chemical corrosive medium.SA709 grade 50W carbon steel material

Quenching Improve the hardness of steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of steel and comprehensive mechanical properties.

SA709 grade 50W carbon steel material,Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.

SA709 grade 50W carbon steel material,If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
