Hardening

Cincinnati Steel Treating offers a variety of hardening options. From tool steels to forgings, CST is your hardening headquarters. We can harden most steels and irons, along with certain stainless steels and non-ferrous alloys.

Cooling from the hardening temperature is a crucial step in the hardening process. Depending on the chemistry of the parrticular material, CST will employ any one of the quenching methods available (air, oil, polymer or water), to achieve the desired results.

Most hardening is performed in an atmosphere neutral to the base carbon of the material being processed. When hardening previously carburized parts the atmosphere is conditioned to be equal to the carbon level of the atmosphere used during caburization.

Cincinnati Steel Treating can perform the hardening process in any one of their five integral quench furnaces, as well as one of their pit furnaces. Parts up to 4000 pounds and as long as 122 inches can be easily hardened.
