Dilibal, H. -950° C. When the nickel alloys are annealed at higher temperatures and for longer periods, a condition commonly described as "dead-soft" is obtained, and hardness numbers will result that are 10 to 20% lower than those of the "soft" condition. The hardness of the edges extends to a significant case depth. 5% before plastic deformation,Ultraelastic Type 60 Nitinol also has the following useful properties: hardness that is adjustable from about 22RC up to about 64RC, low density, high strength (at higher hardness heat treats), low modulus, takes a fine surface finish, low CTE, low thermal conductivity, corrosion resistant, and non-magnetic. Nitinol alloys exhibit two closely related and unique properties: shape memory and superelasticity (also called pseudoelasticity). Nitinol alloys are rapidly becoming the materials of choice for use in self-expanding stents, graft support systems, filters, baskets and various other devices for interventional procedures. , resistivity, hardness, etc.  Nitinol- an acronym for the elements from which the material was composed; ni for nickel, Ti for titanium and nol from the Naval Ordnance Laboratory
