Special Material Fasteners
High-performance fasteners manufactured in nickel alloys, titanium alloys, duplex stainless steels and other special materials for corrosion resistance, heat resistance, strength and demanding industrial service conditions.
Corrosion Resistant
Suitable for aggressive chemical, marine and offshore environments.
High Temperature
Engineered for high-heat service and demanding thermal conditions.
High Strength
Available in precipitation hardening and advanced alloy grades.
Custom Grades
Support for special alloy fasteners based on material and application requirements.
Product Overview
Special Material Fasteners are designed for applications where standard carbon steel or stainless steel fasteners cannot fully meet service requirements. These fasteners are produced in a wide range of nickel alloys, titanium alloys, duplex stainless steels, precipitation hardening stainless steels and other high-performance materials to support demanding industrial environments.
They are widely used in petrochemical systems, offshore engineering, aerospace, high-temperature equipment, energy projects, marine systems and precision industrial applications that require superior corrosion resistance, heat resistance, strength or specialized mechanical performance.
