Q: I’m running a process that has a huge swing in temperature fluctuations due to downtime and maintenance. The max temperature is around 1500F. Can you suggest a material that can handle this?
A: For processes that are faced with the dual dilemma of both high temperature and cyclic conditions, I would recommend alloy 330 bolts. Alloy 330 fasteners are known for their ability to perform under cyclic conditions of extreme temperature swings. In addition, alloy 330 has a maximum usable temperature of about 2100F which is well within your range. Click here for a link to a good mechanical chart for alloy 330 fasteners.
