P460NL2 Pressure Vessel Steel Description

EN10028 P460NL2 Boiler Pressure Vessel Steel is a high-quality, weldable fine-grain steel designed for demanding applications in boiler and pressure vessel fabrication. Known for its exceptional strength and toughness, P460NL2 Pressure Vessel Steel is normalized to enhance its mechanical properties, making it ideal for environments requiring resistance to high pressure and low temperatures.

P460NL2 Boiler Steel is categorized under the EN 10028-3 standard, which includes grades like P355NH, P355NL1, P355NL2, P460NH, and P460NL1. The "NL2" designation indicates that P460NL2 Pressure Vessel Steel is impact-tested at -50°C in the transverse direction, ensuring superior performance in extreme cold conditions.

P460NL2 Pressure Vessel Steel is widely used in the fabrication of boilers, pressure vessels, and pipelines transporting hot liquids, particularly in industries such as petrochemical, chemical, and power generation. Its ability to withstand high pressure and low temperatures makes P460NL2 Boiler Steel ideal for sour gas applications, where it is often HIC-tested to ensure resistance to hydrogen-induced cracking. Additionally, its machinability is comparable to mild steel, facilitating ease of fabrication in complex projects.
