Overall, the mechanical properties of P355NH make it a reliable and durable choice for pressure vessel applications, ensuring the safety and integrity of these components under high-pressure conditions.

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

1. Tensile Strength: The minimum tensile strength of P355NH material is 490-630 MPa, while for P355GH material, it is 510-650 MPa. Tensile strength is the maximum amount of stress that a material can withstand before breaking or fracturing.

2. Yield Strength: The minimum yield strength of P355NH material is 355 MPa, and for P355GH material, it is 355-510 MPa. Yield strength is the stress at which a material begins to deform permanently.

3. Elongation: The minimum elongation of P355NH material is 22%, and for P355GH material, it is 22-31%. Elongation measures the ability of a material to stretch without breaking.

4. Impact Resistance: Both P355NH and P355GH materials have good impact resistance properties, which means they can absorb energy without fracturing or breaking easily.

5. Hardness: Both materials have a hardness value of around 150 HB. Hardness refers to the material’s ability to resist penetration or indentation.

6. Weldability: P355NH and P355GH materials have good weldability, and they can be easily welded using common welding techniques.

It is important to note that these mechanical properties may vary depending on the composition, processing, and heat treatment of the materials. It is advisable to consult the specific material datasheet or manufacturer for accurate and detailed mechanical property information.
