EN 10217-3 P275NL2: Normalized or Normalized-Formed (N) Structural Steel
The steel P275NL2 is a weldable fine-grain structural steel (alloy high-grade steel) that is especially tough to subzero temperature. Tubes made of this steel are used in the pressure vessel construction, apparatus construction, pipeline construction as well as in the general mechanical engineering and device construction.
