Q: Would you be able to quote fasteners, that will used to bolt together multi-piece heat treat racks cast from HX. The racks are used in both solution (water quench and polymer quench) and age furnaces. Our typical temperature range during heat treat cycles is 1300-1800°F but can be as high as 2100°F. Thanks!
A: For this application I would suggest Alloy 330 bolt. Alloy 330 is a very good choice for a heat treat furnace hardware. It offers excellent oxidation and carburization resistant to 2100°F. An alloy 330 bolt is also resistant to thermal shock and quenching. It would be a good bolt for your application.
