Power Generation

Power Generation ComponentsSteloy Castings has solidified its leadership in the production of precision high pressure castings for use in major power generation components and nuclear power plants in the energy sector. We have the advanced technology and know-how required to produce critical components and industrial castings for heat, wear and corrosion resistant applications, particularly in the generation and handling of steam.

Our extensive expertise and technical knowledge working with high temperature, creep resistant materials, including stainless, super alloys and carbon steels, ensures that we are able to satisfy the high demands expected in terms of performance, quality and documentation.

Components for boilers and heaters range from furnace tubes, burners and grids to pump casings, housings and impellers, while the main components for the handling of steam are valve bodies, pump casings, bodies and impellers, primarily for condensation management.

Supplying to major OEMs  in the industry, Steloy offers higher degrees of efficiency for pump assemblies to cater for technically complex and demanding applications and high cycle use. The Steloy casting process enables the design and manufacture of safety critical components, using high integrity moulding methods that ensure the production of consistent castings that eliminate the risk of failure and greatly enhances the primary systems of power plants.

Typical cast components and their material specifications are:

  • Burner nozzles, cast in heat resistant Cr-Ni alloys such as ASTM A297
  • Furnace tubes, in heat resistant  Cr-Ni alloys such as ASTM A608 HK40
  • Wear resistant grids, in BS 3100 gr.BW 3
  • Pump casings, in stainless steel CF8M according to ASTM A734
  • Pump impellers, in stainless steel (17-4PH ) ASTM A747 CB7Cu-1
  • Valve Bodies, in Cr-Mo Steel  ASTM A217 WC9, and
  • General engineering components in Nodular Iron and Flake Graphite Irons.
