Case Applications

Our Case 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 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.

Hardening / Quenching

Our Hardening/Quenching treatments will result in a guaranteed improvement of the mechanical properties of your products, as well as an increase in their level of toughness—making these items more durable. Steel parts often require a specific form of heat treatment to obtain an increase in hardness and strength. And at SST, we are highly-trained in these processes.

Through our Hardening/Quenching treatments, material is heated up to suitable temperatures and then quenched in oil to fully harden, varying on the kind of steel being worked on. Items that go through this are then aged, tempered or stress relieved to achieve the desired stability.




Our Vacuum heat treatments are one of the best processes available in which steel parts are austenitized while under a hard or partial pressure vacuum to protect the surface of the parts during this operation. These processes allow for shorter carburizing cycles, a reduction in overall processing time and smaller gas consumption.

There are numerous treatments involving our Vacuum processes that we use to achieve higher strength and better wear resistance, and to improve the corrosion behavior of the subjected material. At SST, our treatments offer the best protection against oxidation while remaining extremely cost-efficient.




Serving a variety of industry sectors, SST offers a number of Secondary processing services, including deep freezing, tempering, annealing, stress relieving, and the use of cryogenics. All of these methods account for an increase in material hardness and toughness, wear resistance and malleability.

Capable of performing all of these services and more, we’re pleased to accommodate your Secondary heat treating servicing needs. To learn more about these select services, contact SST today.
