2.BS1501 has been superseded by EN 10028. When considering 490A and 490B look for equivalents including ASTM A516 Grade 70 and P355GH BS-224-490A/B is a British Standard specified steel used primarily in the fabrication of weldable steel pressure vessels and boilers.
3.This particular grade which has now been superseded by the Euro Norm standard EN 10028, has improved tensile strength when compared to BS-224-460. As the specification is no longer current, the information included here should be used for reference purposes only.
4.There are two types of BS1501-224-490 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-224-490A/B in the tables below. Current comparable grades are listed in the menu on the left hand side of this web page.
