P355GH

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.

Product Introduction

P355GH is a pressure vessel steel grade as specified under the Euro Norm standard (EN10028) which has superseded British Standard and DIN standard equivalents.

This normalized steel is used worldwide by fabricators of welded pressure vessels, industrial boilers and heat exchangers and is engineered to work well in elevated temperature service.

Properties
Steels for pressure vessels and boilers differ from other carbon-manganese structural steels due to their high resistance to pressure at all temperatures (ambient, low or high).

Advantages
The fundamental property of steels for pressure vessels is their ability to withstand high pressure at different temperatures. They have good weldability, as well as excellent toughness, and are suitable for normalization annealing and stress-relief annealing (both treatments neutralize local hardening caused by welding).

Applications
Steels for pressure vessels are mainly used to manufacture boilers, drums, pressure or steam piping, industrial thermal vessels and heat exchangers. These steels are suitable for mechanical forming and welding.

EN 10028 – P355GH

Widely used throughout the petrochemical industry, P355GH is a pressure vessel steel grade as specified under the Euro Norm standard (EN10028) which has superseded British Standard and DIN standard equivalents.
This normalized steel is used worldwide by fabricators of welded pressure vessels, industrial boilers and heat exchangers and is engineered to work well in elevated temperature service.
We offer grade P355GH from stock and the material is available for shipping to you worldwide. As with all of our steels, the material comes with mill test certification and stamping and is therefore fully traceable. We can also subject the material to a variety of stringent tests prior to distribution.
