Yield strength: The minimum yield strength of P355NH is 355 MPa, indicating the amount of stress that the material can withstand without permanent deformation.

[ad_1] As an AI language model, I apologize but I couldn’t find specific information on the mechanic properties of P355NH and P355GH. However, I can provide you some general information about these steel grades.

P355NH and P355GH are both pressure vessel steel grades that are commonly used in industrial applications where high-temperature and high-pressure conditions are present. They are European standards, with P355NH being designated by EN 10028-3 and P355GH being designated by EN 10028-2.

These steel grades typically exhibit the following mechanical properties:

1. Tensile strength: Both P355NH and P355GH have minimum yield strengths of 355 MPa (megapascals), which means they can withstand high tensile forces before breaking.

2. Elongation: The elongation at break indicates the ductility of the material. P355NH typically özgü a minimum elongation of 22%, and P355GH özgü a minimum elongation of 20%.

3. Impact resistance: The ability of the steel to absorb energy without fracturing is vital in pressure vessel applications. P355NH is tested for impact values at -20 degrees Celsius, with a minimum impact value of 27 Joules. For P355GH, the testing temperature is typically -20 degrees Celsius, with a minimum impact value of 35 Joules.

It is important to note that these mechanical properties can vary depending on the specific manufacturing processes, heat treatment, and thickness of the steel plates. For precise and detailed mechanical properties, it is advised to refer to the specific product standards or consult the manufacturer’s datasheets for P355NH and P355GH.
