Base metals and joint
State both base-metal designations, thicknesses and whether the operation is joining, repair, buttering or overlay.
Welding consumable procurement
ERNiCrMo-3 vs ERNiCrMo-4 vs ERNiCr-3
These AWS A5.14 classifications belong to different filler-metal families. They are not purchasing substitutes simply because all contain nickel and chromium. Base metals, service, governing code and the qualified WPS/PQR control selection.
Confirm classification, diameter, package, batch documents and manufacturer in the offer.Classification map
Do not buy by a shortened alloy name
This table organizes the RFQ; it is not a filler-selection instruction.
| Classification | Common family reference | Procurement question |
|---|---|---|
| ERNiCrMo-3 | Alloy 625 / UNS N06625 family | Is the WPS qualified for the stated base-metal combination, process and service? |
| ERNiCrMo-4 | Alloy C-276 / UNS N10276 family | Does the project specification require this Ni-Cr-Mo classification for joining or overlay? |
| ERNiCr-3 | Alloy 82 / UNS N06082 family | Is ERNiCr-3 explicitly listed in the WPS and approved consumables list? |
