 a. Due to limited available space, sulphur and phosphorus contents are not listed, but are specified. See appropriate standard for more details.
 b. Structural steels with specified Hardenability Bands.
 c. Vanadium added 0.15-0.25 %.
 d. Boron added 0.0005 % (min).
 e.  It is not practical to directly correlate the various metal designations from country to country, let alone comparing several countries and
 their metal designations; from the view that chemical composition may be similar, but not identical, and that manufacturing technologies may
 differ greatly. Consequently, the cross references made in this table at\re, at best, only listed as a guide to assist in finding comparable metal
 designations, rather than the equivalent metal designations.
 f. Bolting grade.
