Q: I’m in the testing phase of a new application that will require a high strength bolt that has a yield strength of about 220ksi. The biggest problem is that the bolts will also be exposed to burst of high temperature of about 1000F. Is there any material you can suggest that could handle this.
A: Yes, in fact there is a material that is especially made to handle situations like this. MP159 bolts are made of an alloys that is often used by aerospace boosters and turbine engines. It offers a yield strength of about 265 ksi. In addition, MP159 bolts can be used at temperatures up to 1100F for continuous use and slightly beyond for short term interval use.
