Inconel Alloy 725 Chemical Composition Properties, Grade, Charts and Online Pdf

Inconel Alloy 725 is a nickel-chromium-molybdenum-niobium alloy with very high strength and corrosion resistance that can be used in various environmental aplications, including severe conditions like high pressure and corrosive chemicals. The chemical composition is often consisting of nickel (58-63%), chromium (19-22.5%), molybdenum (7-9%), niobium (4-5%), and tantalum (2.75-4%). Given this hybrid, these attributes are highly resistance to pitting, crevice corrosion, and stress-corrosion cracking. The alloy 725 is important in the oil & gas, chemical processing and marine engineering industries. Classification of grades follows ASTM B805 and AMS 5766 standards. Tables, charts and PDF files that cover all of its mechanical features, heat treatment recommendations, and fabrication procedures aim at ensuring effective use of the material in the environments that frequently call for its help.

Inconel Alloy 725 Chemical Composition And Grade Table

Inconel Alloy 725 is a nickel-chromium-molybdenum-niobium alloy that is widely appreciated for its high magnitude strength and corrosion resistance in aggressive surrounding. Its chemical composition is typically composed of nickel (58% min), chromium (19-22.5%), molybdenum (7-9%), niobium (2.75-4%), iron (5.5% max), with trace amounts of aluminum, manganese, silicon, sulfur, and carbon being added. This alloy possesses superior mechanical properties under high temperature conditions, thus suitable for oil and gas industry, chemical manufacturing and seawater environments where corrosion resistance and high strength are vital.

Advantages and Disadvantages of Inconel Alloy 725

    Advantages:

  • High strength: It is especially appreciated for its high tensile strength and for its great fatigue resistance.

  • Good weldability: It helps to ease the fabrication and the welding process which are important in ship building.

  • Corrosion resistance: Resists corrosion particularly in harsh environments that may be typically be characterized by high temperatures, high humidity or extreme corrosive conditions.

  • Versatility: They can be appropriate for many services such as chemical processing services and they can as well be used in oil and gas.

    Disadvantages:

  • Limited availability: It is also understand that certain sizes and forms may be available more easily than others.

  • Cost: May be slightly more costly particularly if compared to regular building materials.

  • Sensitivity to hydrogen embrittlement: Possibly, there is a possibility of having hydrogen embrittlement under some circumstances.

  • Limited temperature range: This element of performance may drop off after a certain temperature threshold of either extreme is reached.
