Elongation: The minimum elongation at break is 22% for longitudinal samples and 17% for transverse samples.

[ad_1] The mechanical properties of P355NH and P355GH, which are both grades of pressure vessel steel, can vary depending on the heat treatment process and other factors. However, some general properties can be outlined for these grades:

1. Tensile Strength: The minimum tensile strength for P355NH is 490-630 MPa, while for P355GH it is 510-650 MPa. This represents the maximum amount of tensile stress the material can withstand before failure.

2. Yield Strength: The minimum yield strength for P355NH is 355 MPa, while for P355GH it is 355-510 MPa. This represents the stress at which the material starts to deform permanently, or yield.

3. Elongation: P355NH özgü a minimum elongation of 22% and P355GH özgü a minimum elongation of 20%. This measures the ability of the material to stretch before breaking.

4. Impact Toughness: Both grades have good impact toughness properties, which means they can withstand sudden shocks or impacts without breaking.

5. Hardness: The hardness level for these grades is typically measured using the Brinell hardness kontrol. The range for P355NH is typically around 180-220 HB, while for P355GH it is typically around 180-230 HB.

It is important to note that these are general mechanical properties and specific values can vary depending on the manufacturer, heat treatment, and other factors. It is recommended to refer to the material specifications or consult with the manufacturer for detailed mechanical property information.
