Benefits and Uses of Alloy 20 Fasteners

Alloy 20 fasteners have become an increasingly popular choice for many industrial applications due to their corrosion resistance & cost-effectiveness. Alloy 20 Fasteners are made from a nickel-iron-chromium alloy containing molybdenum, which makes them highly resistant to corrosion caused by sulfuric acid also alloy 20 fasteners can be used in processing chemicals, plastics, food and beverages, pharmaceuticals, and pickling operations.

The high nickel content of Alloy 20 fasteners provides excellent corrosion resistance in chloride-containing environments such as pulp mill bleach plants & seawater cooling systems. In addition to its superior corrosion resistance properties, Alloy 20 offers outstanding strength at elevated temperatures compared to other alloys. 

Uses of Alloy 20 Fasteners

  • Alloy 20 fasteners are used in chemical processing equipment, such as acid production & pickling equipment, due to their excellent corrosion resistance to sulfuric, phosphoric, and nitric acids.
  •  They are used in the pharmaceutical industry for processing equipment, tanks, & heat exchangers that are exposed to harsh chemicals and high temperatures.
  • Alloy 20 fasteners are used in pollution control equipment, such as scrubbers and catalytic converters also used in marine applications, such as seawater piping and marine exhaust systems, due to their corrosion resistance.
  • They are used in the oil and gas industry, in sour gas & oil production, heat exchangers, and other components.
  • Alloy 20 fasteners are used in nuclear power plants, such as pressurized water reactors, due to their high-temperature resistance & corrosion resistance.
  • They are used in the pharmaceutical and food processing industry for equipment exposed to harsh chemicals and high temperatures also used in the paper and pulp industry for equipment like digesters, bleach plants, and recovery boilers.

Benefits of Alloy 20 Fasteners

Excellent Corrosion Resistance: Alloy 20 is a nickel-chromium-molybdenum alloy that offers excellent corrosion resistance to sulfuric, phosphoric, & nitric acids and other aggressive environments.

High Strength and Toughness: Alloy 20 has a high level of strength & toughness, even at high temperatures.

Good Weldability: Alloy 20 can be welded using various methods, including gas tungsten arc welding & gas metal arc welding.

High-Temperature Resistance: Alloy 20 can withstand high temperatures, making it suitable for high-temperature applications such as furnace components & jet engine parts.

Low Thermal Expansion: Alloy 20 has a low coefficient of thermal expansion, which can help prevent distortion and crack during heating and cooling cycles.

Good Formability and Machinability: Alloy 20 can be easily formed and machined, making it ideal for various industrial applications.

Low Carbon Content: alloy 20 has low carbon content, which makes it resistant to sensitization and carbide precipitation during welding, this improves the corrosion resistance of the alloy.

Cost-Effective: Alloy 20 is a cost-effective alternative to other nickel-based alloys, as it offers similar corrosion resistance at a lower cost.
