Everything You Need to Know About Alloy 20
Alloy 20 is a super alloy, sometimes referred to as Carpenter 20, which essentially combines stainless steel (iron and chromium) with nickel. In laymen’s terms, alloy 20 mixes structural integrity and corrosion resistance with a high level of malleability.

Applications for Alloy 20
The nickel content in alloy 20 is very substantial. This means it could be considered both a nickel alloy and a type of stainless steel. It also means that alloy 20 has nearly unmatched resistance to corrosion and oxidation, especially at high temperatures. Its resistance makes it an ideal material for valves and pipe within:
- power plants
- oil and gas refineries
- petrochemical processing
- chemical plants
- food processing
Located in central New Jersey, James Duva, Inc. has been providing rare alloys to American and international clientele since 1978. We are the most knowledgeable alloy 20 pipe distributor on the eastern seaboard.
