1) Use of this table is limited to carbon carbon and low-alloy steel backing materials. 2) For overlay not involving involvi ng clad restoration, use the t he combination of consumables that results in the desired weld metal chemical composition in the top layers. 3) E/ER308 and E/ER316 are not normally normally used in the post weld heat-treated heat-treated condition. The end users users shall approve the use of non-low-carbon E/ER308 and E/ER316 in the post weld heat-treated condition. 4) Eni-1 or ERNi-1 may be used as an alternate.
