Need Invar 36 with better Temperal Stability

Is there a recognised specification for Invar which will give a product that gives temperal stability better than 2 ppm per year after heat treatment? Is there anyone who stocks and/or supplies this grade of Invar?

Sorry, Julie: I, for one, don't understand the question. Hopefully another reader will.
