| a.
The minimum weight % of copper in the rod or electrode due to any coating
plus the residual copper content in the steel shall be 0.50 %. |
| b.
Nickel, chromium, molybdenum and vanadium may be present but are not
intentionally added. |
| c.
In this classification, the maximum manganese may exceed 2.0 %. If it does,
the maximum carbon must be reduced 0.01 % for each |
| 0.05
% increase in manganese or part thereof. |
| d.
For this classification, there are no chemical requirements for the elements
listed, with the exception that there shall be no intentional |
| additional
of nickel, chromium, molybdenum and vanadium. |
| Single
values shown are maximum, unless otherwise specified. |
