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.
