Nickel Alloy 20 Is Also Known As Both Alloy 20 As Well As  Carpenter 20. Nickel Alloy 20 Forged Flanges Are A Low-Carbon Containing, Niobium-Stabilized Austenitic Alloy. 
Alloy 20 Reducing Flanges Primarily Contain Elements Such As Nickel, Iron And Chromium In Their Alloy With Additions Of Metal Elements Like Molybdenum And Copper. The ASME B16.5 Alloy 20 Slip On Flange Exhibits Exceptional Resistance To Corrosion In Chemical Environments.

For instance, alloy 20 will resist corrosion especially in those environments that contain chemicals like  nitric acid, phosphoric acid, chlorides and sulfuric acid. Alloy 20 also has good mechanical properties at both ambient as well as elevated temperatures.Alloy 20  is often termed as a superalloy. ASTM B462/ ASME SB462 Uns N08020 Blind Flange has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides as well as in acidic medium or conditions that contain acidic solutions like sulfuric, phosphoric, and nitric acids.

The addition of  niobium in the Alloy 20Cb-3 Weld Neck Flange has been done in order to stabilize the alloy against sensitization and prevention of the resultant intergranular corrosion. The ASTM B462/ ASME SB462 Uns N08020 Blind Flange is also resistant to stress related corrosion cracking.
