Incoloy 901

Incoloy 901

A nickel-iron-chromium alloy containing titanium and aluminum for precipitation hardening and molybdenum for solid-solution strengthening. The alloy has high yield strength and creep resistance at temperatures to about 1110°F (600°C). A substantial iron content enables the alloy to combine high strength with good forging characteristics. Used in gas turbines for discs and shafts. Standard products form is round.

Description

Corrosion Resistance

Alloy 901 has good corrosion resistance to the atmospheres normally found in jet engine operations. It has slightly lower scaling resistance than such alloy as Types 309 and 310 stainless steel.

Heat Treatment

Solution Treatment
1975/2025°F (1080/1107°C), hold 2 hours at heat, and water quench.

Stabiliztion Treatment
1400/1475°F (760/802°C), hold 2 to 4 hrs, and air cool.

Precipitation Hardening Treatment
1300/1375°F (704/746°C), hold for 24 hours, and air cool.

Workability

Hot Working
Alloy 901 is forged between 2050°F (1121°C) and 1850°F (1010°C), metal temperature. Light hot work may be continued down to 1600°F (871°C) but not below. Metal temperature should not exceed 2050°F (1121°C) during rapid working. Billets should be charged into a hot furnace and heated rapidly through the precipitation hardening range.

Weldability
Alloy 901 can be welded by the inert-gas-arc method. It is difficult to weld. All welding should be done in the solution treated condition. Cold worked parts should be re-solution treated before welding. A re-solution treatment is recommended after welding before stabilizing and aging.

    Incoloy Round Forging Bar

    Sagar Steel Centre is a leading manufacturer and exporter of high-quality nickel-based alloys, including Incoloy 800, or more specifically, its variants 800H and 800HT, which offers excellent high-temperature strength and resistance to oxidation and other types of high-temperature corrosion. Incoloy 800 is widely used in furnace components and equipment, petrochemical furnace cracker tubes, pigtails and headers, and sheathing for electrical heating elements.

    The forging process for Incoloy 800 is typically carried out between temperatures of 2200/1600ºF (1200/870ºC), with heavy forging occurring in the range of 2200/1850ºF (1200/1010ºC). However, special attention must be given to the temperature range of 1400/1000ºF (760/540ºC), where chromium carbide precipitation can occur. To prevent this, parts should be cooled rapidly through the temperature range.
