Description

Steel 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).

This material data has been provided by ArcelorMittal.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
