How Are Cast Steel Retaining Rings Made?

Short Answer:

Tenfaye manufactures custom cast steel retaining rings weighing 1 ton or more, using ZG230-450 steel, with in-house casting, heat treatment, machining and UT/MT inspection. These components support stationary blade installation inside steam turbine casings, helping maintain the structure of the turbine's steam flow path.

What Matters in Retaining Ring Manufacturing?

1.Casting simulation and defect prevention

Retaining rings have complex annular structures, where uneven cooling can cause shrinkage defects or deformation. Tenfaye uses Huazhu CAE casting simulation to analyze filling and solidification, helping optimize gating and riser designs before pouring.

2.Heat treatment and dimensional stability

Stable material properties are essential for components exposed to steam pressure differences and thermal cycling. Tenfaye uses a natural-gas heat treatment furnace to help control the casting's microstructure and mechanical properties, supporting reliable service performance.

3.Integrated machining and quality inspection

Tenfaye completes casting, heat treatment, machining and inspection in-house. UT and MT inspections are available to the specified levels, including UT Level 2/3 and MT Level 2. Chemical composition, mechanical property, inspection reports and heat treatment records can accompany shipments. Customer or third-party inspection at the factory is welcome.

Conclusion

For turbine manufacturers and engineering companies, a reliable retaining ring starts with controlled casting and ends with verified quality. Tenfaye supports drawing-based customization and technical cooperation for heavy cast steel components used in steam turbines and new energy equipment.
