DESCRIPTION

- Commodity name: GH3128 board
GH3128 is a nickel-based alloy strengthened by solid solution of tungsten and molybdenum and strengthened by boron and zirconium at the grain boundary. It has high plasticity, high creep strength, good oxidation resistance, stamping and welding properties.

Overview

GH3128 is a nickel-based alloy strengthened by solid solution of tungsten and molybdenum and strengthened by boron and zirconium at the grain boundary. It has high plasticity, high creep strength, good oxidation resistance, stamping and welding properties. Its comprehensive performance is better than similar nickel-based solid solution alloys such as GH3044 and GH3536. Suitable for manufacturing combustion chamber flame tubes, afterburner housing adjustment plates and other high-temperature parts of aircraft engines that work for a long time at 950℃

Application

· Aircraft engine combustion chamber flame tube, afterburner housing, and regulating plate

· Structural parts of gas turbine combustion chamber

· Turbine engine combustion chamber parts

· Afterburner combustion chamber parts

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.
