Description

S355M is a weldable fine-grained steel with a min. yield point of 355 N/mm². The steel is applicated in thermo mechanical rolled condition for several types of welded constructions such as fixed and movable storage container, high-pressure pipes, bridge and load-bearing constructions. Subsequent heating above 580°C for thermo mechanical rolled products causes reduction of the strength properties. Application limit: at -20°C is warranted a notch impact energy of 40J (longitudinal test specimen). The carbon equivalent (by arrangement) amounts to: for nominal size: < 16 mm: 0,39% > 16 < 40 mm: 0,39% > 40 < 63 mm: 0,40% > 63 < 150 mm: 0,45% Cold forming: Suitability for cold bending, folding, cold flanging or cold welting has to be agreed. For sheet, strip and wide flat steel in thermo mechanical rolled condition, for nominal thickness (s) up to 12 mm can be warranted the following bending radius values: longitudinal: 2,5 x s transverse: 2 x s Sheet and strip of nominal thicknesses < 8 mm for cold forming of sections is available on arrangement (e.g. for production of hollow sections). Warm forming: thermo mechanical rolled products are unsuitable for warm forming. Surface refineability: S355M has to be suitable by arrangement for hot galnanizing and it has to meet the appropriate product quality requirements.

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.
