Form:

This specification covers a corrosion and heat-resistant nickel alloy in the form of round, square, and flat wire 0.500 inch (12.70 mm) and under in nominal diameter or thickness.

Application:

This wire has been used typically for helical springs requiring optimum resistance to relaxation up to 1000 °F (538 °C) with moderate or relatively low stresses, but usage is not limited to such applications.
