cast steel parts for gas turbines
Our custom cast steel parts for gas turbines are engineered for power generation, aerospace propulsion, and industrial drive systems where extreme thermal stability, creep resistance, and high-pressure integrity are critical. Each component—including turbine casings, stator rings, and combustion liners—undergoes rigorous heat treatment and non-destructive testing (such as X-ray and ultrasonic inspection) to ensure zero-defect performance under continuous high-temperature cycling. Available in specialized heat-resistant alloys and stainless steel grades with fully customizable internal cooling geometries, complex thin-wall structures, and precision-machined mating surfaces. OEM and ODM orders supported with sample production available before mass order commitment.
*Provide your application requirements—such as stress conditions, materials, size range, and even product name. We are always available for customization, so please contact us directly.
