Alloy 20 Fasteners are hardware components made from a nickel-iron-chromium-molybdenum alloy known as Alloy 20, also referred to as Carpenter 20 or Incoloy 20. This alloy exhibits exceptional resistance to various corrosive environments, making it suitable for applications where corrosion resistance is a primary concern. The chemical composition of Alloy 20 typically includes 19-21% chromium, 32-38% nickel, 2-3% molybdenum, 3-4% copper, 0.07% carbon, 2-3% iron, 1-2.5% manganese, and small amounts of other elements like silicon, sulfur, and phosphorus.


One of the key features of Alloy 20 Fasteners is their outstanding resistance to a wide range of corrosive media. They are highly resistant to general corrosion, pitting, and crevice corrosion in acidic and chloride-rich environments, making them suitable for applications in chemical processing, petrochemical, and pharmaceutical industries. Additionally, Alloy 20 Fasteners exhibit excellent resistance to sulfuric acid, nitric acid, phosphoric acid, and other aggressive chemicals, making them ideal for use in corrosive process environments.

Corrosion resistance is not the only advantage of Alloy 20 Fasteners. They also possess good mechanical properties, including high strength and excellent fabricability. They can be easily formed, welded, and machined, allowing for various fabrication processes and ensuring that the fasteners can be tailored to specific application requirements.


Alloy 20 Fasteners are widely used in critical applications where resistance to corrosion is vital. They are commonly employed in chemical processing plants for equipment such as pumps, valves, heat exchangers, and reactors, where they can withstand aggressive chemical environments and high temperatures.
