At Hazlewood Fasteners in Canberra, Australia, our duplex steel bolts are engineered for environments where ordinary fasteners simply cannot endure. Designed to deliver commanding strength, superior corrosion resistance, and unmatched stress tolerance, these bolts are built for the toughest structural and industrial realities. Duplex steel’s dual-phase metallurgy empowers these bolts to thrive in chloride-rich, corrosive, and high-pressure settings—from offshore platforms and chemical plants to advanced marine infrastructure. When the demand calls for sheer mechanical power combined with long-term durability, our duplex steel bolts serve as the unwavering anchor for high-security fastening in aggressive operating atmospheres.
Duplex steel bolts feature a balanced austenitic-ferritic microstructure, combining chromium, nickel, and molybdenum with nitrogen reinforcement for elevated strength and corrosion defense. This metallurgical synergy provides exceptional tensile capacity, impressive yield strength, and superior resistance to pitting, crevice attack, and stress-corrosion cracking. Their structure ensures stable torque retention, elevated fatigue life, and dependable performance under fluctuating thermal and mechanical stresses. Designed for demanding service conditions, duplex steel bolts offer a powerful blend of toughness, wear resistance, and long-life fastening integrity in harsh industrial environments.

Duplex steel bolts serve critical roles across offshore engineering, petrochemical facilities, desalination plants, maritime equipment, oil & gas operations, high-salinity pipelines, pressure vessels, and structural fabrication in corrosive zones. Their resistance to chloride-driven deterioration makes them essential for seawater handling systems, coastal construction, shipyards, and heat-exchanger installations. Ideal for both static and dynamic loading, these bolts support flanged systems, mechanical housings, high-pressure assemblies, and vibrating machinery in harsh service conditions. When corrosion resilience, extreme durability, and elevated structural integrity are non-negotiable, duplex steel bolts deliver steadfast fastening stability under the most punishing industrial extremes.
