P275N 1.0486 Pressure Vessel Steel Properties Description

P275N pressure vessel steels are classified under the EN 10028-3 standard, which specifies flat products for pressure purposes. The "P" in P275N stands for pressure vessel steel, and "275" indicates a minimum yield strength of 275 MPa for plates up to 16 mm thick. P275N Pressure Vessel Steel Plate is a high-quality material designed for pressure vessels and boilers,This non-alloy steel is widely used in industries requiring robust materials to withstand high-pressure environments. Known for its reliability, P275N boiler steel offers excellent weldability and durability.

P275N steel is typically supplied in a normalized condition, enhancing its toughness and resistance to brittle cracking. This steel grade is ideal for applications requiring strength at room temperature. EN 10028-3 P275N pressure vessel steels are widely used in industries such as petrochemical, oil and gas, and power generation. P275N boiler steel is ideal for constructing boilers, pressure vessels, and pipelines transporting hot liquids. Its ability to maintain structural integrity at room temperature makes it suitable for standard pressure vessel applications.
