Compared with traditional stainless steel, Inconel 686 has higher temperature and corrosion resistance. Although stainless steel performs well in general environments, the performance advantages of Inconel 686 are more obvious under extremely corrosive media or high temperature conditions.
Next, let's focus on the advantages of Inconel 686!
UNS NO6686 Corrosion Resistant Alloy Corresponding Grade: UNS NO6686 2.4606
High temperature resistance: Inconel 686 can still maintain high strength and excellent toughness at 1600°F (about 871°C), suitable for equipment that needs to work at high temperatures.
Oxidation resistance: The protective oxide film formed on the surface of the alloy can effectively prevent the penetration of oxygen and extend the service life of the product.
Corrosion resistance: It can resist a variety of chemical media (such as acids, chlorides and environmental stresses), and performs well under harsh conditions, especially suitable for the chemical industry.
