EN 10217-3 Grade P355NL2 – Normalized or Normalized Formed (+N) Steel for Low-Temperature Applications

The steel P355NL2 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.
