Oxidation Resistance for Heat Treating

Q: I am interested in 1/4″ x 2 1/2′ bolts and nuts that can resist oxidation up to 2000F. The application they are needed for would be to hold together a steel frame meant to hold tool steel in position preventing distortion during the heat treating process. I would like a recommendation for the best alloy to use in this application.

A: Probably the best alloy to consider in an application like this are Alloy 330 fasteners. This alloy is designed for its high temperature oxidation resistance and stability. Alloy 330 bolts are often used in heat treating applications and would be worth considering.
