This grade is particularly suitable for use in low temperature environments due to its superior toughness and strength. Below is a detailed product introduction that highlights its chemical composition, mechanical properties, heat treatment conditions, low-temperature impact testing, available size range, primary applications, and related supply cases from TJC Steel Group.

Chemical Composition:

EN10028-3 P460NL1 steel plate is characterized by its precise chemical composition, which ensures its excellent mechanical properties and weldability. 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%

· Aluminum (Al): ≥ 0.020%

· Niobium (Nb): ≤ 0.05%

· Vanadium (V): ≤ 0.10%

· Titanium (Ti): ≤ 0.03%

· Boron (B): ≤ 0.005%

· Copper (Cu): ≤ 0.30%

· Nickel (Ni): ≤ 0.80%

· Chromium (Cr): ≤ 0.30%

· Molybdenum (Mo): ≤ 0.10%

Mechanical Properties:

The mechanical properties of P460NL1 are crucial for its application in pressure vessels, especially under high-pressure and low-temperature conditions. The following are the typical mechanical properties:

· Yield Strength: ≥ 460 MPa

· Tensile Strength: 570 - 720 MPa

· Elongation: ≥ 19%

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

Heat Treatment Conditions:

P460NL1 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:

The low-temperature impact test is a critical requirement for materials used in cryogenic applications. P460NL1 steel plates are subjected to impact tests at -40°C, ensuring that the material maintains its toughness and impact resistance at low temperatures.

Available Size Range:

TJC Steel Group offers EN10028-3 P460NL1 steel plates in a wide range of sizes to meet the diverse needs of its customers. The available size range typically includes:

· Thickness: 6mm - 300mm

· Width: 1500mm - 4020mm

· Length: 3000mm - 18000mm

Primary Applications:

The excellent properties of P460NL1 make it suitable for a variety of applications, including:

· Pressure vessels and boilers

· Storage tanks for liquefied gases

· Columns and heat exchangers

· Petrochemical equipment

· Nuclear power plant components
