Key Features of Alloy 617 Fasteners

  • High Strength at Elevated Temperatures: Alloy 617 Fasteners maintain their mechanical characteristics over long periods at elevated temperatures above 1000°C.
  • Outstanding Oxidation Resistance: Inconel 617 Fasteners offer the user significant protection against scaling and oxidation through formation of the protective oxide layer due to high chromium content.
  • Superior Corrosion Resistance: The alloy offers strong resistance to the wide range of both oxidizing and reducing media found in chemical plants.
  • Exceptional Creep Resistance: Inconel Alloy 617 Fasteners remain robust during long-term loading at higher temperatures.
  • Long Life Expectancy: Resistance to corrosion and a lack of material failure reduces maintenance time and replacement costs.
