Super Duplex Steel Fasteners are crafted from high-alloy stainless steel that features elevated levels of chromium, nickel, molybdenum, and nitrogen, resulting in a well-balanced austenitic and ferritic microstructure. This unique composition grants them remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, these fasteners showcase impressive yield and tensile strength, excellent fatigue resistance, and good ductility. They also provide outstanding impact toughness, a high load-bearing capacity, and stable performance even in extreme temperatures and high-pressure situations.
