Corrosion Resistance

 

Nimonic 75 has excellent resistance to corrosion and oxidation. This makes it an ideal choice for applications where exposure to high temperatures and reactive environments is a concern. The alloy is particularly useful in aircraft and maritime applications.

Heat Treatment

For bar products, heat for 30-60 minutes to 1050°C (1920°F) followed by air cooling.

For sheet products, 5-10 minutes at 1050°C F (1920°F) followed by air cooling, or, before welding, 5-10 minutes at 1050°C (1920°F) and air cool, plus an optional 10 minutes at the same temperature followed by air cooling.

WELDING

Alloy 75 should preferably be welded in the annealed condition, and post-weld treatment is not normally necessary unless corrosion conditions are severe. MMA, TIG, MIG and submerged-arc processes may be used, as may electron beam, oxy-acetylene and resistance welding.
