AISI 310MOD Stainless Steel Chemical Composition & Properties, Grades, Table and PDF Online

AISI310MOD is a heat-resistant stainless steel suitable to work in highly corrosive environments at high temperatures. Its chemical makeup is usually around 25% chromium, 20% nickel, and 2.5% molybdenum, which provides an elevated grade of resistance to corrosion and oxidation at temperatures above room during prolonged operations when compared to lower Alloying Steel or AISI 310 grades. This is an alloy which besides having superior strength, creep resistance and thermal stability, is also appropriate for the ion process industries in oil and gas, power generation etc. AISI 310MOD is widely used in a range of industrial and structural applications due to its mechanical or corrosion properties being shown on the chart in order to help the selection of the appropriate material and the engineering design. Such PDF documents being the available primitive source of their composition, grades, and properties are also widely available, which help engineers and manufacturers to leverage this alloy effectively.

AISI 310MOD Austenitic Stainless Steel Chemical Composition And Grade Table

AISI 310MOD is the name of stainless steel version which has characteristic austenitc phase and is more appropriate for usage in extreme condition of either chemicals or in high-temperature. Its chemistry composition is made of about 25% of chromium and 20% of nickel, whereas molybdenum and nitrogen can be added to it. These alloying elements improve its corrosion resistance, as well as especially in the acidic chloride atmosphere prevailing in the processes of oil and gas, chemical processing, and marine applications. AISI 310MOD provides good strength and creep resistance at elevated temperatures which, in turn, allows it to be used in heat exchangers, furnaces, and components that are exposed to high temperatures and prone to corrosion.

The Advantages and Disadvantages of AISI 310MOD Austenitic Stainless Steel


  • High Temperature Resistance: The purpose of 310MOD AISI is to ensure high resistance to temperatures which allow it to be used in heat treatments, furnace components and exhaust systems.

  • Corrosion Resistance: This stainless steel grade is among the premier grades for resistance to corrosion in environments that are extremely aggressive, including those containing acids, alkalis and chlorides.

  • Oxidation Resistance: AISI 310MOD is resistant to oxidation at elevated temperatures and preserves structural values under demanding thermal duties.

  • Strength and Durability: This is characterized by good mechanical properties such as high tensile strength and toughness, which guarantee reliability and durability in different industrial settings.

  • Weldability: AISI 301MOD displays excellent welding properties giving an opportunity to simplify fabrication and assembly in manufacturing.


  • Cost: While at the same time being on the expensive side, AISI 310MOD is a steel grade that may affect the whole budget of the project.

  • Sensitization: Some particular conditions may trigger sensitization, whereby such conditions generate intergranular corrosion, resulting in stricter choice of materials and handling practices.

  • Embrittlement at High Temperatures: Long terms staying in very high temperatures may lead to embrittlement, reduced mechanical properties and structures integrity.

  • Limited Cold Forming: An AISI 310MOD likelihood in cold forming operations may be constrained by its high content of chromium and nickel which usually call for advanced technology.

  • Maintenance Requirements: However, such resistance against corrosion does not mean that AISI 310MOD does not require routine maintenance and cleanup to keep the efficiency and outlook, especially in harsh conditions.
