Product Description
600MW High-Strength Alloy Steel Groove Nuts with Precision Tooth Profile

Our custom groove nuts are specially developed for 600MW steam turbine units, serving as critical high-temperature fastening components for turbine cylinder horizontal joints.

Manufactured from premium high-temperature alloy steel, these groove nuts undergo precision machining and strict heat treatment. They possess outstanding high-temperature strength, creep resistance and fatigue resistance, capable of enduring extreme high-temperature, high-pressure and alternating thermal cycling conditions inside the turbine cylinder.

The unique grooved design delivers uniform pre-tightening force during assembly. It effectively prevents nut loosening caused by thermal deformation and unit vibration, reliably maintaining the sealing tightness of the cylinder split face and eliminating steam leakage risks.

Customization & Quality Assurance

We provide full customization service according to drawings, samples and technical specifications of 600MW turbine projects. Each product is subject to rigorous dimensional inspection and material performance testing to guarantee stable quality and long service life.

Applications: Widely applied in unit overhaul, spare parts replacement and maintenance of 600MW power generation units.
