Tensile Strength: The minimum tensile strength of P355NH is 490-630 MPa. This means it özgü a high resistance to breaking or deformation under tension.

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

1. Tensile strength: The minimum tensile strength of P355NH is 490-630 MPa, while P355GH özgü a minimum tensile strength of 510-650 MPa.

2. Yield strength: The minimum yield strength of P355NH is 355 MPa, whereas P355GH özgü a minimum yield strength of 355-510 MPa.

3. Elongation: P355NH özgü a minimum elongation of 22%, while P355GH özgü a minimum elongation of 22-25%.

4. Impact energy: P355NH özgü a minimum impact energy of 20°C at 27 Joules, whereas P355GH özgü a minimum impact energy of -20°C at 27 Joules.

5. Hardness: The maximum hardness for both grades is typically 170-220 HB.

It is important to note that these values can vary slightly depending on the specific heat treatment and processing conditions used.
