EN10120 P355NB is a weldable fine-grain structural steel compliant with European Standard EN 10120, specifically engineered for manufacturing pressure vessels and gas cylinders. It excels in weldability, mechanical strength, and low-temperature toughness, making it suitable for demanding applications.
Key Applications
Pressure Vessel Fabrication
P355NB is an ideal material for industrial pressure vessels, including gas storage tanks, LPG (liquefied petroleum gas) tanks, and compressed air storage tanks. Its high strength and excellent toughness enable it to withstand high-pressure environments while meeting stringent requirements for welding process compatibility and material performance.
Gas Cylinder Production
It is used to manufacture welded gas cylinders for industrial gases (e.g., oxygen, nitrogen, carbon dioxide) and respiratory cylinders. The material must pass rigorous impact toughness tests to ensure safety under low-temperature or extreme operating conditions.
Mobile Pressure Equipment
P355NB is employed in the construction of vehicle-mounted or shipborne pressure vessels, such as chemical transport tanks and mobile gas storage units. The material must adhere to EN 10120 standards for comprehensive properties, including weldability, fatigue resistance, and corrosion resistance.
