When Exposed to Oxidising Media, Uns N06022 Bolts' High Chromium Content Provides Good Resistance. Astm B574 Uns N06022, for Example, Has Excellent Corrosion Resistance Properties in Oxidising Aqueous Media Environments Such as Wet Chlorine or Mixtures Containing Oxidising Acids Such as Nitric Acid or Chlorine Ions. Hastelloy C22 Nuts Are Resistant to Seawater, Seawater, and Organic and Inorganic Acids, in Addition to These Oxidising Agents. as a result, Hastelloy 22 Fasteners Can Be Used in Marine or Seawater Applications.
Adding Molybdenum and Tungsten to Alloy C22 Fasteners Is Known to Improve Their Resistance to Reducing Media. Nickel Has Good Corrosion Resistance Properties on Its Own. However, When Added to This Hastelloy C22 Screw, It Provides Maximum Corrosion Resistance in Environments with Both Reducing and Oxidising Conditions in Process Streams. This Hastelloy Property Is Useful in Multipurpose Plants Where Mixed Conditions Are Expected.
Hastelloy C22 Bolts' Nickel Content Is Responsible for Preventing the Formation of Grain-Boundary Precipitates in the Weld Heat-Affected Zone. as a result, Hastelloy Fasteners Are Suitable for As-Welded Applications Involving Chemical Processes. Another feature of Hastelloy 22 Is Its Excellent Weldability and Ductility. Hastelloy 22's Ductility Allows It to Be Formed into Various Fasteners Such as Bolts, Screws, Nuts, and So On.
