Power Generation
High-integrity abrasives for turbine blade peening, boiler tube cleaning, and generator component preparation across thermal, nuclear, hydro, and wind power plants — engineered for fatigue and stress-corrosion resistance.
Industry Overview
Reliability for thermal, nuclear & hydro power
Power generation assets run continuously under high temperature, pressure, and cyclic load. Across thermal, nuclear, and hydro plants, surface integrity determines whether rotating and pressure-containing components reach their design life — making peening and surface preparation a core reliability discipline.
Turbine blades are particularly vulnerable to fatigue and stress-corrosion cracking; controlled shot peening introduces compressive residual stress that suppresses crack initiation in wet-steam and high-cycle environments. Boiler tubes and penstocks require clean, profiled surfaces for coatings that resist oxidation, erosion, and cavitation. Macloid Metalix supplies abrasives with certified hardness, chemistry, and sieve analysis on every batch.

Key uses in this industry
Turbine Blade Shot Peening
Steam and gas turbine blades operate under extreme centrifugal and thermal loading where fatigue and stress-corrosion cracking are the primary failure modes. Controlled shot peening introduces a compressive residual stress layer that suppresses crack initiation, extending blade life and improving resistance to stress-corrosion cracking in aggressive steam environments.
- ✓Induces compressive stress to resist fatigue and SCC
- ✓Controlled Almen intensity per SAE J443 saturation curves
- ✓Suited to LP/HP blade roots, fir-tree fixings, and aerofoils
- ✓Coverage verification to specification on critical zones
Recommended media
Cut Wire Shot or Stainless Steel Shot
Boiler Tube Cleaning
Boiler tubes, headers, and economiser sections accumulate mill scale, oxide layers, and fireside deposits that impair heat transfer and mask defects. Steel grit blasting removes scale and oxidation to deliver a clean, profiled surface for inspection, weld overlay, and high-temperature protective coatings in thermal power plants.
- ✓Removes mill scale, oxide, and fireside deposits
- ✓Restores heat-transfer efficiency on tube surfaces
- ✓Prepares tubes for weld overlay and thermal spray coatings
- ✓Achieves Sa 2.5 cleanliness per ISO 8501-1
Recommended media
Steel Grit G18 – G40
Wind Turbine Tower Prep
Wind turbine tower sections require thorough surface preparation before protective coating application. Steel grit blasting removes mill scale and oxidation from rolled steel plates and welded shell sections, creating the anchor profile required by high-build epoxy and zinc-rich primer systems for long-term corrosion protection in exposed environments.
- ✓Sa 2.5 surface preparation of tower section steel plates
- ✓Angular anchor profile for high-build epoxy primer systems
- ✓Suitable for automated blast rooms in tower fabrication facilities
- ✓Supports 25-year design life corrosion protection requirements
Recommended media
Steel Grit G18 – G25
