P355NL1 is a low temperature steel for the manufacture of tanks, boilers, pressure vessels and heat exchangers with a wide working temperature from -40°C to 400°C. It is an unalloyed steel with a minimum yield strength of 355 MPa.

The “P” in P355NL1 stands for “Pressure”, indicating that it is specifically designed for use in pressure vessel applications. The letters “NL” indicate that the steel has low temperature properties, making it suitable for use in applications where the steel will be exposed to low temperatures.

P355NL1 steel is commonly used in the oil and gas industry, chemical process plants, and power generation plants. It is also used in the manufacture of cryogenic vessels, which are designed to store and transport liquefied gases at very low temperatures.

P355NL1 steel has an excellent weldability and is easy to process. It is also resistant to brittle fracture, making it a reliable choice for use in low temperature environments. Overall, P355NL1 is a versatile and reliable steel grade that is well suited for a wide range of industrial applications.
