Description

The non-alloy quality steel P235S is used for simple pressure vessels in the form of normalised or normalising rolled plates, strips and bars. According the directive 87/404/EEC simple pressure vessels are defined as: - every welded, cylindrical vessel with convex and/or flat bottoms made of unalloyed steel with internal pressures between min. 0.5 bar and max. 30 bar, used for air and nitrogen, not exposed to flames - the product of pressure and capacity amounts to max. 10000 bar*l

Equivalent Materials

This material data has been provided by WIAM.

"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.
