Abstract
The intent of this paper was to evaluate a precipitation hardenable stainless steel (Alloy I) as an alternate to chromium cobalt alloys (Alloy II) for orthodontic purposes.
After evaluating several heat treatments of alloy I it was determined that solution treatment produced a wire that was soft initially and had similar properties found with alloy II. After solution treatment of alloy I a 330 gram load was required to deform the wire 1.0 mm which proved to be similar to the 295 gram force required for alloy II for the same deformation and only an 11% increase in resistance of alloy I over that of alloy II.
Following a heat treatment of 950°F for five minutes, alloy I and alloy II became more resistant to deformation requiring a load of 600 grams to cause a deflection of 1.03 mm and 1.45 mm respectively.
This similarity in resistance to deformation after solution treatment and a heat treatment of 950°F between alloy I and alloy II indicates that alloy I when properly processed possess similar properties to alloy II, i.e., soft and easily managed in a nonheat [sic] treated state and the ability of becoming more resistant to deformation, so as to be considered an alternate to alloy II.
