Material Notes:
Fe content above calculated as remainder.

General Elgiloy® information: High strength, ductility, fatigue life, and good mechanical properties. Corrosion resistant in numerous environments. Available in strip (currently 0.0015" to 0.075" thickness and 0.023" to 9.00 " width), round wire (0.006" to 0.625" diameter), sheet, cable, ribbon, bar, rod, and some fabricated parts.

General Forming Notes: Forming should be done prior to heat treatment since heat treatment strengthens the material and makes it more difficult to form. Bending of strip should take place perpendicular to the rolling direction so that it will be across the elongated grain structure rather than parallel to it. In bending strip, a 90° bend should be at least 8 times the material thickness; in a 360° bend, a diameter of 18 to 25 times the material thickness is usually acceptable. Wire should not be formed beyond a mean diameter of 4 times the wire size.

General Joining Notes: Mechanical joining methods are best. Excellent spot welding results have been obtained. When soldering or brazings, a very active flux should be employed and be allowed to remain on the material for a minute or two. When brazing, caution should be exercised to keep temperatures below 593-760°C. Because of this, furnace brazing should be employed whenever possible.
