Power Generation Gas Turbine Materials

Power generation turbines convert the energy of gas into mechanical energy, which is then used to generate electricity. Gas turbines use the expansion of high-pressure gas to drive the turbine blades and produce power. United Performance Metals offers high-performance materials for power generation OEM and aftermarket businesses. Our extensive inventory includes stainless steel, nickel alloys, cobalt alloys, and alloy steel. View the full infographic by clicking here. 

Casing: The casing of a gas turbine plays a vital role in the performance of the turbine, and it is crucial that this material is able to withstand high temperatures and harsh environments. Three of the most common materials that UPM supplies for power generation turbine casings include 718, 625, and CrMoV.

Bearing: The bearings used for gas turbines ensure smooth, low friction rotations. These bearings can withstand high speeds and temperatures and are often made using 718 or L605 materials.

Compressor: The compressor within a gas turbine increases the pressure of the air before it enters the combustion chamber. United Performance Metals offers 718, Alloy X, 422, and L605 materials for compressor applications.

Combustor: The combustor burns fuel to heat compressed air, creating hot, high-pressure gas that drives the turbine. UPM offers 718, 625, Alloy X, C263, Alloy 6230, and 188 for combustor applications.

Turbine: The turbine is a rotary mechanism that converts thermal energy into mechanical energy and drives the turbine’s rotation to generate power. Materials for this application include 718, 625, Alloy 6230, 304, 188, and L605.

Output Shaft: The output shaft connects the turbine to a generator to produce power. Common materials for this application include 718, 625, and Alloy X.
