Tensile Strength: The minimum tensile strength of P355NH is 490-630 MPa, depending on the thickness of the plate.

[ad_1] The mechanical properties of P355NH and P355GH, which are both high-temperature pressure vessel steel grades, are as follows:

1. Yield Strength:
– P355NH: The minimum yield strength for thickness ≤ 16mm is 355 Mpa.
– P355GH: The minimum yield strength for thickness ≤ 16mm is 355 Mpa.

2. Tensile Strength:
– P355NH: The minimum tensile strength for thickness ≤ 100mm is 490 to 630 Mpa.
– P355GH: The minimum tensile strength for thickness ≤ 100mm is 510 to 650 Mpa.

3. Elongation:
– P355NH: The minimum elongation for thickness ≤ 16mm is 22%.
– P355GH: The minimum elongation for thickness ≤ 16mm is 21%.

4. Impact Properties:
– P355NH: The minimum impact energy value at -20°C is 27 Joules.
– P355GH: The minimum impact energy value at -20°C is 27 Joules.

These mechanical properties are important for ensuring the structural integrity and performance of pressure vessels used in high-temperature applications.
