DESCRIPTION

- Commodity name: Incoloy901 forgings
Overview

Inconel 901 alloy is 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 of about 1110°F (600°C). The large iron content enables the alloy to combine high strength with good forging characteristics. Used for discs and shafts in gas turbines. The standard product shape is round.

Chemical composition

Molybdenum Mo: 5.0-6.5, sulfur S: ≤0.008, aluminum Al≤ 0.30, molybdenum Mo: 5.0-6.5, sulfur S: ≤0.008, aluminum Al≤ 0.30, copper Cu≤0.20, titanium Ti≤2.8-3.1, bismuth Bi≤0.0001, lead Pb: 0.001, boron B: 0.01-0.02

Corrosion resistance

Alloy 901 has good corrosion resistance to the atmosphere common in jet engine operation. Compared with alloys such as 309 and 310 stainless steel, its oxidation resistance is slightly lower.

Application

This alloy is widely used abroad for rotating parts and fasteners working below 650℃ on aircraft engines and ground gas turbines, and has a long service life. It is widely used to manufacture rotating disc parts, static structural parts, turbine outer rings and fasteners of aircraft and ground gas turbine engines working below 650℃

A nickel-chromium-molybdenum alloy with the addition of niobium, which acts with molybdenum to harden the alloy matrix, thereby exhibiting high strength properties without heat treatment. The alloy is resistant to various harsh corrosive environments, especially pitting and crevice corrosion. It is used in chemical, aviation and marine engineering, pollution control equipment, and nuclear reactors.

The low carbon alloy 625 after softening annealing is widely used in the chemical process industry, and its good corrosion resistance and high strength make it can be used as a thin structural component. 625 alloys can be applied in contact with seawater and subjected to high mechanical stress. Typical application areas:
1. Components of organic chemical processes containing chlorides, especially where acid chloride catalysts are used;
2. For the manufacture of digesters and bleaching ponds for the pulp and paper industry;

3. The absorption tower, reheater, flue gas inlet baffle, fan (wet), agitator, deflector and flue in the flue gas desulfurization system;

4. For the manufacture of equipment and components used in acid gas environments;
5. Acetic acid and acetic anhydride reaction generator;
6. Sulfuric acid condenser.
