ASTM A182 F55 fasteners consist of a super duplex stainless steel alloy with about 25% chromium, 7% nickel, 3.5% molybdenum, and some small amount of nitrogen, offering very good resistance to pitting and stress corrosion cracking. These fasteners possess great mechanical strength with a tensile strength of at least 795 MPa and yield strength of 550 MPa, as well as greater toughness and hardness. Their austenitic-ferritic composition, which is well balanced, guarantees great performance under severe stress conditions and makes them perfect for applications critical to severe environments.
