BS1501–224–460A/B Pressure Vessel Steel plate
1.Pressure Vessel Steel
BS 1501 161-360A/B | 161-430A/B | 223-490A/B | 224-460A/B | 224-490A/B | 225-490A/B
2.BS1501-224-460A & B are no longer current pressure vessel steel grades. Consider equivalents such as ASTM A516 Grade 65 and P295GH. For use in weldable industrial boilers and pressure vessels, BS-224-460A/B is the British Standard specification which is comparable with ASTM A516 Grade 65.
3.This British Standard has now been superseded by the European specification EN10028 but we still receive enquiries for this specific grade which is why we have included technical information on this website.
4.Please note that this information should only be used for cross-referencing purposes when comparing to current specifications.
5.There are two types of BS1501-224-460 available which are …
Type A :Denotes specified min. room temperature tensile properties
Type B :As per Type A but with elevated temperature properties
Please refer to technical details for BS-224-460A/B in the tables below. Current comparable grades are listed in the menu on the left hand side of this web page.
