DIN 17102 W St E 255 steel is typically applied in fields with high requirements for welding performance and mechanical properties, such as machinery manufacturing, construction, bridges, pressure vessels, and pipeline engineering.
Machinery Manufacturing: WStE 255 steel possesses good welding and mechanical properties, making it suitable for the manufacture of various mechanical equipment and structural components. Examples include drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, and hydraulic supports for coal mines used in mining and various construction projects.
Construction and Bridges: This steel can be used to construct structures such as factories, general buildings, and bridges, providing reliable strength and durability.
Pressure Vessels: WStE 255 steel exhibits stable mechanical properties at high temperatures and complies with relevant standards for pressure vessel manufacturing, such as the AD Pressure Vessel Code. Therefore, it is suitable for manufacturing various pressure vessels that can withstand harsh working conditions such as high temperatures and high pressures.
Pipeline Engineering: For pipelines transporting media such as natural gas and oil, especially in harsh environments (such as the Arctic), the toughness of the steel is extremely important. WStE 255 steel, after normalization treatment, has good toughness and welding performance, meeting the requirements of these special working conditions.
Other Fields: In addition to the aforementioned fields, WStE 255 steel can also be used to manufacture other structural components and parts that require high strength and good welding performance.
