Inconel Alloy 926 Chemical Composition, Grades, Tables and Pdf

Inconel Alloy 926 is a super-austenitic stainless steel tailored for maximum anti-corrosion properties when exposure to corrosive environments is imminent. The chemical composition of a super austenitic stainless steel normally includes nickel, chromium, molybdenum, and nitrogen, thus offering excellent pitting, crevice corrosion, and stress-corrosion cracking resistance. The grades of Inconel Alloy adhere to the numerous international standards for example the ASTM, EN and DIN characteristics which guarantee reliability and quality assurance for operation. Extensive tables, charts and PDF resources that are full of in-depth information relating to its chemical composition, mechanical properties, and corrosion resistance are available from the producers and industry sources. Engineers and materials specialists use these resources to determine the best alloy for the most severe operating conditions in various industries, including chemical processing, marine engineering, and oil & gas.

Inconel Alloy 926 Chemical Composition And Grade Table

The Inconel Alloy 926 is a super-austenitic stainless steel dedicated to providing superior resistant to corrosion in aggressive environments. These metals that it is typically made of, nickel, chromium, molybdenum and nitrogen, give this alloy exceptional hardness, and ability to withstand pitting, crevice corrosion and stress corrosion cracking. The specs of Inconel 926 mentioned in the grade table include ASTM B549 and ASTM A240, among others. This balance between the components provides for mechanical strength even at high temperatures. This alloy uses in different industries such as chemical production, marine engineering and oil and gas production based on its outstanding corrosion resistance.

Advantages and Disadvantages of Inconel Alloy 926


  • Corrosion Resistant: It also means that the protection against corrosion in various hostile surroundings is excellent.

  • High Strength: Temperatures As with most ferrous alloys, it exhibits high strength even under high temperatures.

  • Oxidation Resistant: Shows high resistance in case of oxidation up to 1020°C.

  • Formable: It can be easily deformed and, moreover, welded with application of the standard methods.


  • Cost: As pointed out earlier it is relatively expensive as compared to other stainless steel grades.

  • Machinability: It is hard to machine, which is attributed to its relatively high look strength as well as toughness.

  • Availability: The conspicuous disadvantage of limited availability means that for any company that uses LME as a benchmark, they are bound to experience longer lead times if they attempt to procure this commodity.

  • Thermal Conductivity: Those materials have found to possess lower thermal conductivity than lots of other materials.
