Steel for heat-resistant pressure vessels. P355GH steel gives optimum performance for pressurised products that must support a creep limit greater than 180N/mm2 at 400ºC.
These types of steel are characterised by good weldability. They are used above all for manufacturing boilers, pressure vessels and pipes for the transportation of hot liquids. They also have good properties at high and low temperatures. The product is always supplied in the normalised condition.
