Description

Submerged-arc welded tubes made of the heat-resistant non-alloy quality steel P235GH are used for steam pressure vessels, tube construction, pressure vessel and apparatus manufacturing mainly in the chemical industry for temperatures up to 200 °C and simultaneous high pressures. The total load and the special scale relationships may decrease or increase the temperature limit.

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.
