Impact Energy: P355NH özgü a minimum impact energy of 27 Joules at -20°C. It represents the amount of energy that the steel can absorb before fracturing under impact.

[ad_1] Unfortunately, the mechanical properties of P355NH and P355GH are not specifically provided by the user. However, generally speaking, both P355NH and P355GH are high-temperature pressure vessel steels with good mechanical properties.

Some of the common mechanical properties that may be associated with these steels include:

1. Tensile strength: The maximum amount of stress that a material can withstand before it breaks or fractures. It is usually measured in MegaPascals (MPa).

2. Yield strength: The stress at which a material begins to deform plastically without undergoing any further increase in strain. It is also measured in MegaPascals (MPa).

3. Elongation: The ability of a material to undergo plastic deformation before it ruptures. It is measured as a percentage, representing the increase in length of the material after rupture.

4. Impact strength: The ability of a material to withstand sudden impacts or shocks without fracturing or breaking. It is often measured using a Charpy or Izod kontrol.

5. Hardness: The resistance of a material to indentation or scratching. It is typically measured using a hardness tester, such as the Rockwell or Brinell hardness kontrol.

It is important to note that the specific mechanical properties of P355NH and P355GH can vary depending on factors such as the manufacturing process, heat treatment, and composition of the steel. Therefore, it is advisable to refer to the specific material data sheet or consult with a materials engineer for accurate and detailed mechanical property information.
