ST52 is a structural low carbon steel grade. ;ST52 Steel Tube ;is designed with a chemical composition of carbon, silicon, manganese, phosphorous, and sulfur alongside other alloying materials. This allows the ;ST52 Tube ;to work well in corrosive environments and high-pressure environments. They are designed with a thickness of 5mm up to 300mm. The ;ST52 Carbon Steel Pipe ;is a high strength grade that is available in lengths between 3000mm to 12000mm. These pipes work well across elevated temperatures. The ;ST52 Steel Material ;is designed to possess superior mechanical properties. The material has a minimum yield strength of 355mpa with a tensile strength between 490-630mpa. ;ST52 Pipe ;can be readily elongated by 22% and are a common fixture in food processing, agricultural machinery, earth moving equipment, compressors, pneumatic cylinders, boiler systems, etc.
Piping components in the ST52 grade can be designed in seamless and Erw welded configurations. Both these types can be distinguished from each other on certain key features.
DIN 2391 ST52 nbk is a precision mild or low carbon grade. The ;DIN 2391 ST52 NBK Tube ;is capable of withstanding high temperatures. These tubes are produced in the normalized condition in controlled setups. The ;ST52 S355 Annealed Tube ;is annealed above the upper transformation point. The annealed tubes showcase good tolerance to reducing environments.
