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).
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 normalisation annealing and stress-relief annealing (both treatments neutralise local hardening caused by welding).
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.
