P460NH
1.8935Highest-strength normalized pressure vessel fine-grain steel — ReH >=460 MPa. "N" = normalized, "H" = elevated temperature. Used for high-pressure vessels, boiler drums, and chemical reactors where maximum strength with guaranteed elevated-temperature properties is needed. EN 10028-3 + PED compliant. Good weldability due to fine grain and controlled CEV.
