Over the years, the company has established a standard of S355J2W railway steel steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to S355J2W railway steel quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.

With the rapid development of economy, there are many kinds of engineering projects, and their development is very fast. However, steel is an essential material in construction engineering. At present, there are many kinds of steel products on the market. In order to ensure the construction quality, the requirements for the strength, quality and corrosion resistance of S355J2W railway steel, steel are more and more strict.

Difference between Q345R boiler vessel plate and ordinary Q345 plate, S355J2W railway steel:Q345R boiler vessel plate is pressure vessel steel, Q345 plate is low alloy steel.Q345R boiler vessel plate generally requires flaw detection and positive deviation, while Q345 plate generally has lower requirements.In terms of performance, Q345R boiler vessel plate and Q345 plate are of the same level. However, due to high requirements, they can not be mixed in general.Generally, the requirement of Q345R boiler vessel plate is higher than Q345 plate, S355J2W railway steel.

The steel plate cutting and processing instructions are as follows: steel plate cutting and steel plate cutting processing, as well as S355J2W railway steel steel plate zero cutting processing. There are semi-automatic flame cutting, fully automatic CNC cutting, laser cutting and water cutting. The thickness range of steel plate that can be cut is 20650mm. In terms of S355J2W railway steel steel plate cutting types, there are Q235B common plate, Q345B low alloy plate and 45 carbon bonded plate.
