Description

The non-alloy special steel P275SL 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
