Super Duplex Steel Bolts are crafted from a high-alloy stainless steel blend that includes chromium, nickel, molybdenum, and nitrogen, resulting in a well-balanced austenitic-ferritic microstructure. This unique composition provides outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, these bolts showcase impressive tensile and yield strength, exceptional fatigue resistance, and good ductility. They also deliver excellent impact toughness and maintain their shape under high pressure, elevated temperatures, and harsh environments. These characteristics ensure that bolted joints remain secure and reliable in critical industrial settings.
