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. |
