Material: Inconel® Fasteners – Engineered for Extreme Environments
Overview:
Inconel® is a high-performance nickel-chromium-based superalloy designed to withstand extreme temperatures, aggressive corrosive environments, and high mechanical stress. Known for its unmatched stability and oxidation resistance, Inconel fasteners are a preferred choice in industries where other alloys fail — such as aerospace, chemical processing, and marine engineering.
At SM Fasteners, we supply precision-engineered Inconel fasteners manufactured under stringent quality standards, ideal for critical applications in high-temperature and high-pressure environments.
Why Choose Inconel Fasteners?
Inconel exhibits extraordinary mechanical strength, resistance to thermal creep deformation, and corrosion resistance in both oxidizing and reducing environments — especially at temperatures above 1000°C.
✅ Withstands temperatures up to 1100°C
✅ Excellent oxidation & scaling resistance
✅ Superior resistance to acids (sulfuric, nitric, hydrochloric)
✅ Non-magnetic, high fatigue strength
✅ Ideal for cryogenic to superheated conditions
Grades We Offer
Inconel 600 (UNS N06600) – Excellent strength and resistance to high heat
Inconel 625 (UNS N06625) – Outstanding corrosion and fatigue resistance, especially in marine and chemical exposure
Inconel 718 (UNS N07718) – Precipitation-hardened for exceptional tensile, fatigue, and creep-rupture strength
Inconel X-750 (UNS N07750) – Great for springs and fasteners at elevated temps
