17-4PH Bolts for High Strength

Q: I have equipment that requires a high strength bolt. Temperature and corrosion are not an issue, solely strength. I had tried Super Duplex thinking that would do the trick, but I’m still having breakage. Any ideas?

A: For an application that exclusively requires high strength, you might want to consider 17-4PH bolts. 17-4PH is an age hardened steel that provides extreme strength ranging from 160-200ksi (ultimate tensile strength) depending on the level of heat treatment. 17-4PH bolts have a yield strength that can be up to 2- 1/2 times greater than Duplex 2205 and over 4+ times greater than 316 stainless steel.
