These mechanical properties make P355NH suitable for applications requiring good weldability and high tensile strength, such as pressure vessels and boilers operating at elevated temperatures.

[ad_1] P355NH is a pressure vessel steel grade that is commonly used in the fabrication of boilers, pressure vessels, and heat exchangers. It is specifically designed to withstand high-pressure and high-temperature conditions.

Mechanical properties of P355NH include:

1. Tensile Strength: The minimum tensile strength of P355NH is 490-630 MPa, depending on the thickness of the plate. This indicates the maximum amount of tensile stress the material can withstand before breaking.

2. Yield Strength: The minimum yield strength of P355NH is 355 MPa. It is the amount of stress the material can withstand before it starts to deform plastically or permanently.

3. Elongation: The minimum elongation of P355NH is 22% (on gauge length of 5x thickness). Elongation measures the ability of the material to stretch without breaking.

4. Impact Strength: P355NH özgü a minimum impact strength of 27 Joules at a temperature of -20°C. This indicates how well the material can resist sudden shocks or impacts.

5. Hardness: P355NH özgü a maximum hardness of 150 HB. Hardness is a measure of the material’s resistance to indentation or scratching.

These mechanical properties make P355NH suitable for applications in the oil and gas industry, chemical industry, and power generation sector, where high-pressure and high-temperature conditions are common.
