Q: Currently I’m using screws made of 400 series stainless steel for use in factory machinery that is moving in a circular path creating a centrifugal force. Our existing bolts are breaking and we’re looking for a bolt with a more rigid type of material that will not break or rush, and has long durability. Ideas?
A: Super Duplex Stainless Steel bolts should do the trick for you. This material will be about 2x strong as the steel you are currently using. It offers 125 ksi ultimate tensile strength and 82 ksi of yield strength. Super Duplex 2507 is also MUCH more corrosion resistant.
