P355NH is a pressure vessel steel grade that is commonly used in the fabrication and construction of boilers, storage tanks, and pressure vessels. It is known for its excellent mechanical properties, which include:

[ad_1] The mechanical properties of P355NH and P355GH are as follows:

1. Tensile strength: P355NH özgü a minimum tensile strength of 490-630 MPa, while P355GH özgü a minimum tensile strength of 510-650 MPa.

2. Yield strength: P355NH özgü a minimum yield strength of 355 MPa, while P355GH özgü a minimum yield strength of 355-510 MPa.

3. Elongation: P355NH özgü a minimum elongation of 22%, while P355GH özgü a minimum elongation of 22-27%.

4. Impact energy: P355NH özgü a minimum impact energy of 27 J at -20°C, while P355GH özgü a minimum impact energy of 27 J at 0°C.

5. Hardness: P355NH özgü a hardness range of 140-190 HB, while P355GH özgü a hardness range of 150-190 HB.

These mechanical properties are important for applications that require high strength, good yield strength, and excellent impact resistance. P355NH and P355GH are both used in pressure vessel and boiler applications where these properties are critical for the safe operation of the equipment.
