Product Description
As a key component of the connection and support structure,
high-temperature hex nuts play a crucial role in ensuring the normal operation and efficient performance of steam turbines. High temperature hex nuts are mainly used in high-temperature parts of steam turbines, such as high-temperature blades, high-temperature cylinder bodies, etc., to maintain the stability of key parts of the turbine and ensure the normal operation of the system.
The high-temperature hex nuts used for steam turbines are made of special high-temperature alloy materials, which have excellent high-temperature strength, anti loosening, corrosion resistance, and oxidation resistance.
The commonly used special high-temperature alloys for steam turbines include 15CrMoA, 35CRMOA, 40CrMoV-5, 45Cr1MoV, 0Cr18Ni9, 1Cr11Co3W3NiMoVNbNB, 1Cr18Ni9Ti, 20Cr1Mo1VNbTiB, 20Cr1Mo1VTiB, 25Cr2MoVA, 2Cr11Mo1NiWVNbN, and 2Cr12NiMo1W.
The manufacturing of high-temperature hex nuts requires precise process control to ensure their precise dimensions and meet high quality standards. Quality control is crucial throughout the entire manufacturing process. By using various inspection techniques such as size measurement, metallographic microscopy, ultrasonic testing, etc., ensure that each hex nut meets the specification requirements.
