Annealing Instructions:
2050°F for 4 hours in pure dry hydrogen atmosphere, followed by cooling at 400°F per hour down to 1100°F. Then cooling rate can be accelerated. Exposure to normal atmosphere can occur below 600°F.

Maintenance:
Because of its high nickel content, this alloy is highly corrosion resistant. Cleaning is simple with a soft cloth, or you can use mild soapy water (be sure to rinse well and dry). If required for cosmetic purposes, this material can be spray painted or adhesive veneers may be applied.
