Tensile strength: The minimum tensile strength of P355NH is 490-630 MPa, depending on the thickness of the material. This property determines the ability of the steel to withstand external forces without breaking.

The mechanical properties of P355NH and P355GH are as follows:

P355NH:
– Tensile strength: 490-630 MPa
– Yield strength: 355 MPa
– Elongation: 22%
– Impact energy (transverse): Min 27 J

P355GH:
– Tensile strength: 510-650 MPa
– Yield strength: 355 MPa
– Elongation: 20%
– Impact energy (transverse): Min 27 J

These properties indicate the strength, ductility, and impact resistance of the materials. They are important for determining the suitability of P355NH and P355GH for various engineering applications.
