INTERNATIONAL CLASSIFICATION |
AWS/ASME: NONE
EN14700 E Fe15
DIN 8555: E10-UM-60-GRZ
FEATURES & APPLICATIONS |
For protecting most iron base surfaces against severe abrasive wear and moderate impact.
- Chromium carbide electrode for economical smooth overlays.
- Ripple free surface doubles “grip resistance” to fine abrasive media.
- 3/32(2.5mm) and 1/8(3.2mm) provide position capability.
- Special formula totally eliminates the “Worm Tracking” type porosity common to this alloy group.
- Also available as a special tubular MIG wire as product code 7251.
All Weld Metal Analysis (Typical Weight %) |
Microstructure: In the as-welded condition, the microstructure consists of an austenitic alloy matrix (bulk hardness RC57) and chromium/complex carbides (hardness RA 77).
