EN 10028-3 P460NL1 Boiler And Pressure Vessel Steel Plate

Overview

EN 10028-3 P460NL1 is a normalized fine-grain steel plate designed for pressure vessels, boilers, and structural components requiring high strength and good low-temperature toughness. It is widely used in industries such as oil & gas, petrochemical, power generation, and cryogenic storage.

Key Features

1. High Strength & Toughness

Minimum yield strength (ReH) = 460 MPa

Tensile strength (Rm) = 570–720 MPa

Excellent impact resistance at -50°C (NL1 grade).

2. Weldability

Fine grain structure ensures good weldability (preheating may be required for thick plates).

Compatible with common welding methods (SMAW, SAW, GTAW, etc.).

3. Normalized Condition (N)

Heat-treated by normalizing (heated to 890–950°C and air-cooled) for improved mechanical properties.

4. Low-Temperature Suitability

NL1 designation means it meets Charpy V-notch impact energy ≥40 J at -50°C, making it suitable for cryogenic applications.

EN10028-3 P460NL1 Steel Plate is widely used in the manufacture of welded pressure vessels and structural components operating in low-temperature or ambient environments due to its high strength and excellent toughness at both low and elevated temperatures. Examples of its applications include:

1. Petrochemical Industry: Ethylene spherical tanks, propylene spherical tanks, liquefied gas storage tanks, hydrogenation reactors, and tower vessels.

2. Gas Industry: Cryogenic storage tanks for liquid oxygen, liquid nitrogen, liquefied natural gas (LNG), and other low-temperature liquids.

3. Energy and Power: Boiler drums, non-nuclear pressure components in nuclear power equipment.

4. Heavy Machinery: High-strength structural components for large engineering machinery.
