The comprehensive mechanical properties of P355GH steel welding process, Q345B steel plate are good, the low temperature performance is acceptable, and the plasticity and weldability are good. Q345B steel is used for medium and low pressure containers, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures that bear dynamic loads, mechanical parts, building structures, general metal structural parts. Plate Q345B is the most versatile and the most used pressure special steel plate for container.The company always adheres to the p355gh steel welding process principle of "quality first, user first", and takes every cooperation seriously. It is our biggest wish that the steel material, specification and quantity can fully meet the requirements of users. With good reputation, high quality products and low price, we are willing to work together with old and new customers to create a great p355gh steel welding process cause. Customers are welcome to visit our company at any time. We are always ready to support you.Try to use p355gh steel welding process high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the p355gh steel welding process temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion,p355gh steel welding process., API 5L X60 steel plate is one mainly of Steel for large diameter pipes, API-X60 steel for the manufacture of buried pipelines for transporting natural gas can succumb to severe degradation due to corrosion by the soil through. The types of corrosion of steel that can be produced are often general corrosion and pitting.The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel.
