Due to Inconel 600 hex nuts’ corrosion resistance, temperature stability, toughness and strength, they are widely used in chemical processing, aerospace, marine, electronics and oil and gas industries.

As a leading inconel 600 hex nut manufacturer, KD Fasteners, Inc.’s line of Inconel 600 hex nuts are made with a nickel-chromium alloy resulting in good oxidation resistance at higher temperatures and good resistance in carburizing and chloride containing environments.inconel 600 hex nut

Inconel 600’s high nickel content enables our Inconel 600 hex nuts to retain considerable resistance under reducing conditions and makes them resistant to corrosion by a number of organic and inorganic compounds. The nickel content also gives Inconel 600 excellent resistance to chloride-ion stress-corrosion cracking and provides excellent resistance to alkaline solutions.

The chromium content of Inconel 600 gives the alloy resistance to sulfur compounds and various oxidizing environments. As a result, Inconel 600 hex nuts resist steam and mixtures of steam, air and carbon dioxide.
