1) Use of this table is limited to carbon and low-alloy steel backing materials.

2) For overlay not involving clad restoration, use the combination ofconsumables that results in the desired weld metal chemical compositionin the top layers.

3) E/ER308 and E/ER316 are not normally used in the post weld heat-treatedcondition. The end users shall approve the use of non-low-carbonE/ER308 and E/ER316 in the post weld heat-treated condition.

4) Eni-1 or ERNi-1 may be used as an alternate.
