BS1501 – 161-360A/B
BS-161-360A/B (often referred to as Grade 360A/B) is a British Standard specified steel which is ideal for use in fabricated steel pressure vessels and boilers.
The BS specification has now been superseded by the Euro Norm specification EN 10028, however, many companies in the industry still refer to this standard, so we have included details of the grade for cross reference purposes.
There are two types BS1501-161-360 available which are …
- Type A :
Denotes specified min. room temperature tensile properties - Type B :
As per Type A but with elevated temperature properties
