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

[ad_1] The mechanical properties of P355NH and P355GH, which are both European steel grades for pressure vessel steel, can vary slightly. However, they generally have the following mechanical properties:

1. Tensile Strength: The tensile strength of P355NH is typically between 490 MPa and 630 MPa, while P355GH generally özgü a tensile strength ranging from 510 MPa to 650 MPa.

2. Yield Strength: The yield strength of P355NH is usually around 355 MPa, hence the name, while P355GH typically özgü a yield strength of about 355 MPa as well.

3. Elongation: The elongation at break for both grades is usually around 22%, meaning that the material can stretch up to 22% of its original length before breaking.

4. Impact Resistance: P355NH and P355GH are both known for their good impact resistance properties, making them suitable for applications in pressure vessels and other high-pressure environments.

5. Hardness: The hardness of P355NH and P355GH can vary, but it is generally in the range of 150 to 220 HB (Brinell hardness) or 149 to 240 HV (Vickers hardness).

It is important to note that these values are approximate and can vary depending on the manufacturing process and specific alloy composition. Moreover, these mechanical properties are provided for informational purposes only and should not be used as specifications without consulting the official standards or the manufacturer’s documentation.
