Alloy 20 is an iron - and nickel-based alloy developed to resist sulfuric acid corrosion. Its resistance to sulfuric acid corrosion is excellent; It is also highly resistant to phosphoric acid, nitric acid and chloride environments, chloride stress corrosion, point corrosion and crack corrosion. It is widely used in chemical, food, medicine, power generation and plastics industry.

 

Alloy 20 (1) is an iron-based austenitic alloy developed to resist sulfuric acid corrosion. It has excellent resistance to sulfuric acid corrosion; Phosphoric acid, nitric acid and chloride environment, chloride stress corrosion, resistance to point corrosion and crack corrosion are very strong. Therefore, alloy 20 has the name of corrosion resistant alloy; It has a wide range of applications: such as: chemistry, food, medicine, electricity production and plastics industry will use it. Resistance to point corrosion and chloride corrosion, stress corrosion cracking problems, etc., often choose alloy 20.

 

The chemical composition of alloy 20 is:

Iron 31-44% (balanced)

Nickel 32-38.00%

Chromium 19-21.00%

Molybdenum 2-3.00%

Copper 3-4.00%

Manganese 2%

Silicon 1%

Niobium (8.0xC),1% largest

 

Alloy 20 exhibits impressive mechanical properties. Its tensile strength is around 80 ksi, with a yield strength of 35 ksi. Alloy 20 also has good ductility and toughness, making it ideal for use in challenging environments.

 

Depending on its intended use, Alloy 20 can undergo various heat treatments to enhance its properties. For example, annealing at temperatures between 1600°F and 1900°F can improve its toughness and ductility, while also reducing its hardness and strength. Conversely, quenching and tempering can result in a harder, more durable material ideal for applications that require superior wear resistance.

 

Alloy 20 has a wide range of applications across several industries. Its corrosion resistance makes it ideal for use in chemical processing plants, where it can withstand exposure to sulfuric acid and other corrosive chemicals. It is also used in the construction of heat exchangers, boilers, and other equipment that requires superior corrosion resistance.
