Steels for steam turbine blades we produce:
Steel used for steam turbine blades is typically a high-performance alloy that is designed to withstand the high temperatures and stresses of the turbine environment. These alloys are usually based on nickel, cobalt, or iron, and may contain a variety of other elements, such as chromium, molybdenum, and tungsten.
One commonly used alloy for steam turbine blades is Inconel, which is a nickel-chromium alloy that exhibits excellent high-temperature strength and resistance to oxidation and corrosion. Another popular alloy is Hastelloy, which is a nickel-molybdenum-chromium alloy that is known for its exceptional resistance to a wide range of corrosive chemicals and environments.
The specific properties of the steel used for steam turbine blades will depend on the requirements of the turbine design and the operating conditions of the turbine. Some key properties that are typically desired include high strength, high resistance to corrosion and oxidation, good fatigue resistance, and excellent dimensional stability.
The manufacturing process for turbine blades involves a combination of casting, forging, and machining operations to produce a finished product with the required shape and properties. Quality control is critical throughout the manufacturing process to ensure that the finished blades meet the necessary specifications and can perform reliably in the demanding turbine environment.
