Yield Strength: The minimum yield strength of P355NH is 355 MPa, which means the steel can withstand a certain amount of stress before permanent deformation occurs.

[ad_1] The mechanical properties of P355NH and P355GH are as follows:

– Tensile strength: 490-630 MPa
– Yield strength: 355 MPa
– Elongation: 22%
– Impact energy: 27J at -20°C

– Tensile strength: 510-650 MPa
– Yield strength: 355 MPa
– Elongation: 20%
– Impact energy: 27J at 0°C

Both P355NH and P355GH are high temperature pressure vessel steels. They have good weldability and high resistance to brittle fracture. These properties make them suitable for use in power plants, boilers, and other high-temperature applications.
