EN10028-3 P460N is a pressure vessel steel grade that is widely used in the fabrication of pressure vessels and boilers due to its excellent mechanical properties and resistance to high temperatures. This grade is compliant with the European standard EN10028-3, which specifies requirements for flat products for pressure equipment made of weldable fine-grain steels.

Chemical Composition:

The chemical composition of P460N is carefully controlled to ensure the necessary mechanical properties and weldability. The typical chemical composition is as follows:

· Carbon (C): ≤ 0.18%

· Silicon (Si): ≤ 0.50%

· Manganese (Mn): ≤ 1.60%

· Phosphorus (P): ≤ 0.025%

· Sulfur (S): ≤ 0.015%

· Nickel (Ni): ≤ 0.70%

· Chromium (Cr): ≤ 0.30%

· Molybdenum (Mo): ≤ 0.08%

· Copper (Cu): ≤ 0.30%

· Niobium (Nb): ≤ 0.05%

· Titanium (Ti): ≤ 0.03%

· Vanadium (V): ≤ 0.05%

Mechanical Properties:

The mechanical properties of P460N are characterized by high strength and toughness, which are essential for pressure vessel applications. The typical mechanical properties are as follows:

· Yield Strength: ≥ 460 MPa

· Tensile Strength: 570 - 720 MPa

· Elongation: ≥ 19%

· Impact Energy (at -20°C): ≥ 40 Joules

Heat Treatment:

P460N steel plates are generally supplied in the normalized condition. Normalization is a heat treatment process that involves heating the steel to a temperature above its upper critical point and then cooling it in air. This process refines the grain structure and improves the mechanical properties of the steel.

Low-Temperature Impact Test:

P460N is subjected to a low-temperature impact test at -20°C to ensure that the material maintains its toughness and impact resistance at low temperatures. This is crucial for applications where the equipment may be exposed to cold environments.
