Seamless pressure steel tubes

Steel grade: P235GH TC1, P355N TC1
Standard: EN 10216-2, EN 10216-3
Material certification: EN 10204:3.1
Delivery mode: GH (hot metal), N (normalized)
Dimension range: outside diameter 13,5 - 660mm / wall thickness 1,8 - 100mm

P235 GH is a heat-resistant, non-alloyed pressure steel, mainly used in piping systems conveying hot liquids. The main applications are steam boilers and pressure vessels.

P355N TC1 is a fine alloy steel used in high pressure applications where it is necessary to ensure proper impact resistance of the steel at high temperatures.
