P275N Steel Description
P275N steel is a normalized pressure vessel steel plate under the EN 10028-3 standard, designed for moderate and high-temperature service conditions. With a minimum yield strength of 275 MPa, it provides good ductility and toughness, making it ideal for pressure-containing components such as boilers, storage tanks, and heat exchangers.
Thanks to its excellent weldability and mechanical stability, P275N is a preferred choice for manufacturers in the oil, gas, chemical, and power generation industries. The steel can be supplied in hot-rolled, normalized, or normalized rolled condition, ensuring consistent performance and long service life.
