Alloy 718 Fasteners

Alloy 718 provides very high strength with good corrosion resistance.

Precipitation hardening is required to achieve tensile strengths exceeding 200 ksi.

Fasteners are used in environments from -400º F (-250º C) to 1300º F (700º C).

Stock: High-strength fasteners available for extreme temperature applications.
