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.
