Case Hardening & Applications

Our Case Hardening and Application processes increase strength and wear resistance by diffusing carbon, through a number of different methods, into the surface of steel parts. This creates a casing around the material while retaining a substantially lesser hardness inside the core. At SST, we’re experts when it comes to steel heat treatments such as this — these intricate processes are applied to low carbon steel parts after machining, as well as high alloy steel bearings, gears and other crucial components.
