Incoloy 901 is a nickel-iron-chromium alloy that contains titanium and aluminium for precipitation hardening. This alloy has excellent corrosion resistance and high strength at elevated temperatures, making it an ideal material for use in various applications such as gas turbines, aircraft engines, and nuclear reactors. In this article, we will discuss the properties, composition, and applications of Incoloy 901 along with its equivalent grades. Chemical Composition of Incoloy 901 The chemical composition of Incoloy 901 is as follows:
- Nickel (Ni) – 42%
- Iron (Fe) – 35%
- Chromium (Cr) – 12.5%
- Titanium (Ti) – 5.5%
- Aluminium (Al) – 2.3%
- Carbon (C) – 0.10% max
- Manganese (Mn) – 0.50% max
- Silicon (Si) – 0.60% max
- Sulfur (S) – 0.015% max
- Phosphorus (P) – 0.015% max
The presence of titanium and aluminium in this alloy promotes the formation of gamma prime (γ’) phase which contributes to the precipitation hardening of this alloy. Mechanical Properties of Incoloy 901 The mechanical properties of Incoloy 901 are given below:
- Tensile strength – 135 ksi (930 MPa)
- Yield strength – 110 ksi (760 MPa)
- Elongation – 15%
- Reduction of Area – 20%
- Hardness – Rockwell C 37 (max)
These properties make this alloy suitable for use in high-stress applications where exceptional strength and toughness are required. Forms of Incoloy 901 Incoloy 901 is available in several forms including:
- Pipe
- Plate
- Strip
- Round bar
- Wire
The most commonly used form of Incoloy 901 is the round bar. It is available in diameters ranging from 0.25 inches to 16 inches. Other forms such as pipes, plates, and strips are also available, but their usage is limited. Process Service of Incoloy 901 Incoloy 901 can be hot or cold worked depending on the requirements. Hot working is typically performed at temperatures between 1800°F and 2200°F (980°C and 1200°C), while cold working can be done at room temperature. This alloy has poor welding characteristics, so it is generally not recommended for use in applications where welding is required. Standard Specification of Incoloy 901 Incoloy 901 is covered by several standard specifications, including ASTM B408, AMS 5660, and BS HR 55. The ASTM B408 specification covers the standard requirements for hot-finished or cold-finished nickel alloy bars and rods, while AMS 5660 covers the same for bars, wire, forgings, rings, and extrusions. BS HR 55 specifies the requirements for nickel alloys, including Incoloy 901, for use in aerospace and other high-performance engineering applications.
