EN10028-3 P460NH is a pressure vessel steel grade with excellent mechanical properties and chemical composition, specifically designed for applications at low temperatures. This grade is widely used in the fabrication of welded pressure vessels and boilers where notch toughness at low temperatures is a critical requirement.

Chemical Composition:

EN10028-3 P460NH steel plate is characterized by its precise chemical composition, which ensures its high performance under pressure and at low temperatures. The typical chemical composition is as follows:

· Carbon (C): ≤ 0.16%

· Silicon (Si): ≤ 0.50%

· Manganese (Mn): ≤ 1.50%

· Phosphorus (P): ≤ 0.025%

· Sulfur (S): ≤ 0.015%

· Nickel (Ni): ≤ 0.70%

· Chromium (Cr): ≤ 0.30%

· Molybdenum (Mo): ≤ 0.08%

· Niobium (Nb): ≤ 0.05%

· Titanium (Ti): ≤ 0.03%

· Vanadium (V): ≤ 0.05%

Mechanical Properties:

The mechanical properties of P460NH are crucial for its application in pressure vessels. The following are the typical mechanical properties:

· Yield Strength: ≥ 430 MPa (at room temperature)

· Tensile Strength: 570 - 720 MPa

· Elongation: ≥ 19%

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

Heat Treatment:

P460NH is 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:

The material is subjected to a low-temperature impact test to ensure that it maintains its toughness at sub-zero temperatures. The impact energy values are measured at -20°C, which is a standard temperature for such tests, but the material can also be tested at other temperatures as per specific requirements.
