What is the difference between Inconel 625 and ss316?
Inconel 625 Features
Inconel 625 is a nickel-based superalloy that offers excellent corrosion resistance in both high and low temperature environments. It has excellent strength over a wide temperature range, from cryogenic to 2200°F (1000°C). It also has good oxidation resistance, making it ideal for applications that require high temperatures or corrosive environments. Inconel 625 is also non-magnetic and has good machinability.
316 Stainless Steel Features
316 Stainless Steel is an austenitic stainless steel alloy that has a higher molybdenum content than other austenitic stainless steels, such as 304 stainless steel. This increased molybdenum content gives 316 stainless steel better corrosion resistance from chloride ion solutions, such as seawater, than most other stainless steels. This makes it ideal for applications in saltwater or chemical processing plants where chloride ions are present. In addition, 316 stainless steel has good formability and weldability when using fusion or TIG welding processes.
Difference between Inconel 625 and 316 Stainless Steel
Inconel 625
Inconel 625 is a nickel-chromium-molybdenum alloy with the addition of niobium. This provides the alloy with enhanced strength and corrosion resistance. The alloy is resistant to a wide range of corrosive environments, including those containing chlorides, sulfuric acid, and hydrochloric acid. It also has good resistance to pitting and crevice corrosion.
316 Stainless Steel
316 Stainless Steel is an austenitic chromium-nickel alloy with the addition of molybdenum. This provides the alloy with enhanced corrosion resistance, especially to pitting and crevice corrosion. The alloy is also resistant to chloride stress corrosion cracking and has good resistance to intergranular corrosion.
Composition
The main difference between Inconel 625 and 316 stainless steel is their composition. Inconel 625 contains nickel, chromium, molybdenum, niobium, and iron, while 316 stainless steel contains chromium, nickel, molybdenum, and iron. This gives Inconel 625 better strength and corrosion resistance than 316 stainless steel.
Applications
Inconel 625 is commonly used in chemical processing, aerospace engineering, offshore engineering, and power generation, while 316 stainless steel is used in food processing, medical equipment, and construction applications.
