EN10219-1 S355k2H LSAW Welded Steel Pipe
EN 10219-1 S355K2H submerged arc welded steel pipe is a structural longitudinal submerged arc welded steel pipe produced according to the European standard EN 10219-1. Its material grade is S355K2H.
S355K2H welded steel pipe is a low-alloy high-strength structural steel with a yield strength usually around 355 MPa and a higher tensile strength. This steel has good toughness, weldability and corrosion resistance, making it suitable for a variety of structural applications.
EN 10219-1 S355K2H longitudinal submerged arc welded steel pipe is widely used in various structural projects, including bridges, buildings, oil and gas transmission pipelines, water treatment facilities, mechanical equipment, etc.

a. The deoxidation method is designated as follows: FF: Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen (e.g. min. 0,020 % total Al or 0,015 % soluble Al). b. The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % with a minimum Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document. |
