As a result of being active in the forging industry for many decades, the experienced staff of Prosteel Supply can provide you with the best suitable product from our qualified suppliers. Based on the required amount, dimensions, delivery time, mechanical specifications and test requirements, we know what producer will meet and exceed our customers demand.


Forged rings and bushings are the specialty of Prosteel Supply and we can provide you with a large variety of products, starting from outside diameters of 150 mm up to 7.800 mm.

Rough forged rings
These products are forged and heat treated according to specification, without and additional machining. Ideal for customers who need quality parts for further in-house machining. The average allowance on final dimensions is 10-30 mm and after steel blasting these parts are suitable for non-destructive testing.

Pre-machined rings
Rings and bushings forged, heat-treated and machined with an maximum allowance of 1-3 mm. on final dimensions. These parts are used by customers that want to do the final machining in-house or wanting to have the flexibility to make last-minute design adjustments to the products.

Complete machined rings
Steel rings or bushings that have been forged, heat-treated and machined / drilled to the customers drawing and other specifications. These parts are ready to be further assembled by the customer without any in-house machining. It is also possible to supply complete machined rings with cladding (overlay welding), surface treatment (hardening), coating (protective or decorative), etc.


Test certificates are evenly important as the forged products themselves to ensure our customers that they are getting exactly the products as ordered. Therefore, Prosteel Supply offers a complete range of test methods on all products required. Whether it is a basic 3.1 certificate or a third party inspection according to DNV or any other authority, we can provide exactly what is required.

Some of our testing methods at a glance:

  • Hardness and tensile testing
  • Ultrasonic testing
  • Dye penetrant testing
  • Magnetic particle testing
  • Grain size testing
  • PMI – Positive Material Identification
  • Ferrite measurements
  • Corrosion esting
  • CTOD testing

Open-die forging

The most common supplied forged parts range between 200 kg. and 15 tons, however, Prosteel Supply can supply you with a large range and variety of forgings, in an almost unlimited range of materials.
