I have an application that is notorious for breaking bolts. It's a carbon steel guard fastened to a carbon steel housing. The current fastener are 316SS. I am weighing the option of using high strength fasteners. If they were metric the obvious choice would be A4-80 but that is not so easily found in SAE. I can get 450 stainless fasteners. Crevice corrosion should not be an issue. Any thoughts or experience with 450 SS in submerged saltwater applications?
