Key Benefits

Some of the key benefits you can expect when using AMASTEEL are:

  • Lowest consumption
  • Highest productivity, lowest cost
  • Consistent abrasive performance
  • Reduced wear
  • Reduced dust and waste disposal
  • Local technical support

The Ervin technology for high carbon steel abrasives is the most advanced in the world. We manufacture to third party international specifications in Glaubitz, Germany.

This ensures AMASTEEL shot and grit is a consistently high quality martensitic abrasive. Continuous quality control, in combination with the cutting-edge production process, optimises durability and cleaning power.

After-Sales Support

Steel abrasive is not a commodity. It is an essential component in a process that can be very costly if not maintained and supported on a regular basis.

Our trained technical support personnel are therefore at your disposal, at no additional cost. We can arrange to visit relevant plants as required on a regular basis to provide:

  • Advice on abrasive selection
  • A review of machine settings to ensure reduced wear and optimum abrasive consumption
  • Assessment of abrasive performance and work-mix configuration
  • Assessment of cleanliness and, if required, surface roughness on work-pieces
  • Advice on potential cost savings and productivity increases

Steel shot blasting

Ervin can come to your assistance if you require world-class steel shot blasting solutions. Steel shot blasting is the ideal surface preparation method and is commonly used to remove sand, scale, rust, oxide, previous coatings and more. Steel shot blasting goes by many different names and is also referred to as shot blasting and abrasive blasting. The process often takes place in a blast room and automatic wheel machine and can be used to clean, strengthen and prepare metal. Surfaces can also be cleaned with grit before they are coated. Shot blasting is an environmentally friendly option that is used in a wide range of industries including the automobile sector, aerospace, rail and many more.

A cleaner, smoother surface

Steel shot blasting ensures scale, rust and other coatings are completely removed from a surface so new coatings can adhere to the steel. You can expect the coating to fail unless it is added to a clean and properly prepared metal surface. In steel shot blasting, steel is fired against the surface with compressed air or by machine blasting. Steel shot blasting is ideal for cleaning, smoothing and roughing a surface. The shots are delivered at high velocity so the right results can be achieved.

What happens during steel shot blasting?

During the process, small particles between 0.125-3mm in diameter are propelled against the surface. The bigger the pellets are, the rougher the surface will be. Opting for smaller shots will give you a smoother and more polished finish. Chilled iron grit can be used for certain metals but is not a suitable match for softer surfaces like aluminium. There are two main shot blasting technologies in use today, and these are wheel blasting and air blasting.
