Alloy 20 or carpenter 20 is the material that is chromium, nickel, and iron-based austenitic alloy. It is crafted for ensuring the higher resistance to the acid attacks, particularly to the sulfuric acid. This material is having very good resistance ability to the general corrosion, crevice corrosion and pitting as well. Also, it resists sulfuric acid, phosphoric acid, and nitric acid. Also, it is containing niobium for the stabilization against the sensitization. Alloy 20 is combining very good resistance to the elevated mechanical; attributes and fabrication ease. Basically, this material is designed for its use in the sulfuric acid associated industries.

The manufactured ranges of Alloy 20 Sheets & Plates are having many good properties to offer because of which it has become a perfect fit for different purposes. The properties found in it are high tensile strength, good dimensional accuracy, superior surface finishes, rugged construction, high toughness, long functionality, non-corrosive body, withstand high temperature, etc.
