W48.2-M1992 (R1998)

Scope

1.1
This Standard prescribes requirements for the classification and certification of chromium and chromium-nickel covered steel electrodes for shielded metal arc welding.
This includes electrodes designated for welding heat-resistant steels containing more than 11% chromium and less than 50% nickel.

1.2
Electrodes specified in this Standard are classified according to the
(a) chemical requirements of undiluted weld metal (Table 1);
(b) electrode covering and the usability characteristics of the electrode (Table 2); and
(c) mechanical properties of the weld metal, in the as-welded condition (Table 3).

1.3
Any electrode certified under one classification is not certified under any other classification.

Note: The classification system is explained in Clause A1.2 of Appendix A.

1.4
The values given in SI (metric) units are the standard. The inch/pound (Imperial) equivalents are given in parentheses and
are for information only. In case of dispute, the metric values rule.
