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P355GH is a pressure vessel steel grade as specified under the Euro Norm standard (EN10028) which has superseded British Standard and DIN standard equivalents.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