As a steel supplier in China,we can offer all kinds of steel stock,offer P355N steel stock,the best price of P355N steel ,P355N steel is a normalized, weldable fine grain steel for pressure purposed. The dimensions and tolerance on dimensions should be according to EN 10028-1.
P355N steel is a normalized, weldable fine-grain structural steel designed for pressure applications. It provides excellent mechanical properties, including proper yield strength, tensile strength, creep resistance, plasticity, and toughness, along with good cold forming and heat treatment performance.
Gnee Steel can supply P355N steel in a variety of dimensions, with tolerances following EN 10028-1, ensuring suitability for high-pressure boilers, vessels, and other harsh environment applications.
Key Characteristics of P355N Steel
- Excellent mechanical properties: high yield and tensile strength, toughness, creep resistance.
- Good cold plastic deformation and formability.
- Excellent weldability and heat treatment response.
- Corrosion resistance and oxidation resistance suitable for harsh environments.

What is the difference between P355GH and P355NH?
P355GH: This steel is designed for high-temperature applications and is characterized by high strength at temperatures up to 500 °C. P355NH: This steel is designed for low-temperature applications and is characterized by high toughness at low temperatures.
What is P355GH equivalent to ASTM material?
P355GH pressure vessel steel is an equivalent to ASTM A516 Grade 70 and ASME SA516 Grade 70.
What is P355NH material?
A pressure vessel steel grade with good weldability and high resistance to brittle cracking, P355NH is used by the world's fabricators for the manufacture of pressure vessel tanks for the storage of pressurised gases.
What is the temperature range of P355NH?
Its most widespread use is in application environments up to 400 ºC. P355NH steel is supplied in the normalised condition. The normalising temperature is 900 - 950 ºC, and it must be left in the furnace after temperature equalising for approximately 1 minute per millimetre of thickness of the plate.
