Alloy 20 Wires Supplier

What are Alloy 20 Wires?

These wires contain nickel-iron-chromium alloy. Also, these wires show excellent corrosion resistance in acidic environments, including sulphuric, phosphoric, and nitric acids. Also, this wire offers resistance to stress corrosion cracking in chloride-rich environments. The alloy 20 wires can be fabricated and welded through the most conservative processes while maintaining resistance to pitting and crevice corrosion. Alloy 20 Wires offer resistance to the hostile environment. These wires have outstanding mechanical properties and can be fabricated with comparative ease.

Chemical Composition Alloy 20 metal:

  • Nickel
  • Chromium
  • Iron
  • Copper
  • Molybdenum


Why is Alloy 20 used?

Alloy 20 contains niobium elements for standardization. Niobium increased the corrosion resistance properties of Alloy 20. This alloy is also composed of chromium and nickel. This chromium element has excellent corrosion resistance over a wide range of fluids. The element nickel shows good resistance to chlorinated corrosion. Alloy 20 offers high resistance to pitting and crevice corrosion. Also, the alloy shows resistance to sulfuric acid. This alloy is a special grade of stainless steel.


Features of Alloy 20 Wires:

  • High corrosion resistance
  • High strength
  • Easy to use
  • Comparatively quick
  • Work at high temperatures and pressure

Properties of Alloy 20 Wires:

Alloy 20 Wires have excellent essential corrosion resistance, sulfuric acid protection, and chloride stress rust cracking ability. Also, it has good mechanical qualities and fabricability, minimal carbide precipitation for the duration of welding, and excels in resisting corrosion to very hot sulfuric acid. 

Application of Alloy 20 Wires:

These alloy 20 wires are used in the oil & gas, fertilizer, petrochemical, power plant, sugar, chemical, and shipbuilding industries.
