Hardface grinding can be a challenge without the correct tools for the job. Eagle Superabrasives manufactures and supplies superabrasive wheels that meet the specific needs of customers looking to grind hardfacings.

We keep a minimum of 6,000 wheels in stock and create custom diamond and CBN wheels, ensuring that you have the right wheel for any job. We ship stock orders same day and some custom orders in as little as seven days.

What Is Hardface Grinding

As the name implies, hardfacing is used to limit wear of metal parts by hardening their surface. Metal parts often fail and fall short from their intended use not because they fracture, but because of wear which causes the loss of dimension and functionality.

Hardfacing is also referred to as hardsurfacing, and works by applying build-up or wear-resistant coatings or materials to a part’s surface.

Which Materials Can Use a Hardface Grinding

Hardface grinding can be done on low alloy steels with carbon contents of less than 1%.

A few of the metals that can be hardfaced are:

  • stainless steels
  • manganese
  • cast irons
  • nickel- and copper-based alloys

Which Are the Processes Used to Hardface Materials

There are many processes used to hardface a part’s surface, including:

  • flux cored arc welding (FCAW)
  • gas metal arc welding (GMAW)
  • shielded metal arc welding (SMAW)
  • submerged arc welding (SAW)
  • gas tungsten arc welding (GTAW)
  • oxyfuel welding (OFW)
  • plasma transferred arc welding
  • laser welding
  • thermal spray
  • brazing

Which Metals Are Usually Used In Hardface Grinding

Carbon and low-alloy steels are the most common metals used to hardface other materials. With that being said, determining the type of wear your equipment may encounter will help you determine what metal to use.

Hardfacing can be a huge saver of both time and money if your equipment is subject to severe wear through repeated impact.

Grinding Hardface Wheels

Hardface grinding requires wheels that are specially engineered to take on such a task. Eagle Superabrasives chemists and engineers work constantly on developing diamond wheels that make hardface grinding a breeze.

We do so by using our proprietary bonds specifically designed for hardface and hardened alloys.

Which Industries Use Hardface Grinding

Steel, cement, mining, and the oil and gas industries are just a few of many that have utilized hardfacing to their benefit.

In these industries, the parts simply do not last long enough without hardfacing, with the causes below usually being the culprit:

  • Abrasion – 40%
  • Impact – 25%
  • Metallic – 5%
  • Heat – 5%
  • Corrosion – 5%

Hardfacing can be applied using thermal spraying, spray-fuse and welding processes. Once the layer is applied, it takes a heavy-duty superabrasive to grind down the surface for maintenance.

Eagle’s diamond wheel lineup is perfect for tackling the complex challenge of working on hardface materials. We have the perfect bond for your application, and can consistently repeat it time and time again.
