Incoloy020

Incoloy 020 alloy has good corrosion resistance to sulfuric acid chemicals and good resistance to environmental corrosion such as chloride, phosphoric acid and nitric acid. It resists intergranular corrosion by sensitization and syneresis with stable niobium-containing elements, and has good mechanical properties and workability.

incoloy020 corresponding grades: NS1403,NS143,20NB, 0cr20ni35Mo3Cu3Nb, American Standard: incoloy020, Alloy20, No8020, German Standard: 2.4660, nicr20cumo, Nicrofer3620NB. incoloy020 corrosion resistance: good corrosion resistance in concentrated sulfuric acid below 50 degrees, more than 50 degrees above Shanghai Longjin is not recommended, in wet phosphoric acid, hydrochloric acid is not an ideal choice of material, resistance to intergranular corrosion and pitting corrosion is not good. Physical properties: density 8.1g/cm3, melting point: 1350 ~ 1370 ℃, specific heat capacity: 500J/kg.K, thermal conductivity: 13.5. W (m.K), modulus of elasticity: 200 MPa incoloy020 processing and welding: alloy hot forming temperature in 970 ~ 1065 degrees, should not be in the intergranular corrosion 650 degrees sensitive temperature for forming operations, this alloy cold processing molding similar to chromium-nickel stainless steel. Heat treatment should be stabilized at 940 degrees, intermediate annealing temperature in higher than 1050 degrees solid solution softening annealing treatment, can be welded using the usual welding methods. incoloy020 application areas: in the chemical processing industry, hot seawater and wet metallurgy has been widely used. Mainly used for heat exchangers, pipes, valves, pumps, etc. in the handling of hot sulfuric acid, solutions containing chlorides, sulfurous acid and other environments
