Description:AFM NI-55 is designed for welding cast iron, malleable iron and ductile iron to themselves and other wrought alloys, including nickel alloys. A core wire chemistry of approximately 55% nickel and 45% iron produces weld deposits with much lower weld shrinkage stress which in turn reduces the possibility of weld or heat-affected zone cracking.
Applications: AFM NI-55 is especially suited for welding heavy sections such as motor blocks, housings, machine parts, frames, defective castings and building up worn sections. Stringer deposits are generally harder to machine due to the dilution of the weld metal, however heavier beads and multiple layer welds will exhibit good machinability.
All values are considered maximum, unless otherwise noted.
Typical Mechanical Properties of Undiluted Weld Metal:
- Tensile Strength,psi 58,000-84,000
- MPa 400-579
- Elongation, (%) 6-18
