EN10028-3 P275N Pressure Vessel Steel Plate

​EN10028-3 P275N steel plate is a pressure vessel grade steel for use in low temperature applications. It is typically used in the fabrication of welded pressure vessels and industrial boilers where the added advantage of good weldability and high strength is advantageous.
Chemical Composition:
The chemical composition of EN10028-3 P275N is strictly controlled to ensure the material's mechanical properties and weldability. The typical chemical composition is as follows:

• Carbon (C): ≤ 0.16%
• Silicon (Si): ≤ 0.35%
• Manganese (Mn): ≤ 1.50%
• Phosphorus (P): ≤ 0.025%
• Sulfur (S): ≤ 0.015%
• Aluminum (Al): ≥ 0.020%
• Niobium (Nb): ≤ 0.05%
• Titanium (Ti): ≤ 0.03%
• Vanadium (V): ≤ 0.05%

Mechanical Properties:
The mechanical properties of P275N are characterized by its excellent strength and toughness. The following are the typical mechanical properties:

• Yield Strength: ≥ 275 MPa
• Tensile Strength: 430 - 580 MPa
• Elongation: ≥ 22%
• Impact Energy (at -20°C): ≥ 40 Joules

Heat Treatment:
P275N 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:
P275N is designed for applications at low temperatures, and as such, it must pass a low-temperature impact test. The material is tested at -20°C to ensure that it maintains its toughness and impact resistance at cold temperatures.
Available Dimensions:
TJC Steel Group offers EN10028-3 P275N steel plates in a wide range of sizes and thicknesses. The typical available dimensions are:

• Thickness: 6mm - 300mm
• Width: 1500mm - 4000mm
• Length: 3000mm - 18000mm

Main Applications:
