Our Markets

Sullivan Steel supplies steel for demanding performance applications where strength, longevity, and corrosion resistance is critical. You can find our steel used on a range of items from critical engine bearings to aircraft parts to food processing blades. Extreme temperatures, salt water, or endless heat cycles; Whatever the challenge, we have a steel that will meet your uniquely challenging application.

Below are some the major categories that benefit from the materials we carry:

Aerospace & Military

Aircraft quality bearing material is where we got our start in 1980. It’s an industry we know very well; we’ve worked with major aircraft parts manufacturers to supply steel for critical bearings and shafts that can not fail. This level of quality has helped us expand our metals into the critical military and aerospace markets as well.


  • Bearings
  • Ball Screws
  • Helicopter Shafts
  • Landing Gear Components
  • Hydraulic Parts
  • Gas Turbine Parts
  • Military Weaponry

Formula One & Motorsports

F1 Car

Few industries push the limits of metals more so than motorsports. The motorsport grades we carry have extensive use in Formula 1, arguably the most demanding of them all. Extreme temperatures and RPMs can turn the average metal into shreds; fortunately, we have solutions. Our steels can take the constant abuse that winning requires; while meeting some of the most complex design requirements on the planet. Once available to only those with Formula 1 connections, these steels are now available through Sullivan’s US distribution, and at a growing number of size and quantities. Perfect for short run, high performance applications that require the best.
