Heat Treating Services

Cincinnati Steel Treating (CST) performs solution treating, aging, stress relieving, and annealing of cast and wrought aluminum products.

Annealing is used to soften or alter the grain structure for improved formability and machinability.

Whether your parts require glass bead blasting or steel shot blast cleaning, CST accommodates many different parts, including forged and fragile items.

Carbonitriding introduces ammonia as well as carbon into the furnace atmosphere for hardening steel.

CST has an extremely broad range of furnaces for both job shop and production gas carburizing, including nitrocarburizing and carbonitriding.

FNC is a case hardening process similar to gas nitriding that is used to produce a hard, wear-resistant surface on low grades of steel such as 1010, 1018, 1020, A-36, etc. and most cast irons.

Cincinnati Steel Treating has a vast array of knowledge and experience with flame hardening. Consult with our flame hardening experts to determine the best solution for your application.

For gas nitriding, our Ohio facility is well located for Midwest manufacturers, offering one of the largest nitriding departments in the country.

CST offers a variety of hardening options. From tool steels to forgings, CST is your hardening headquarters.

Cincinnati Steel Treating has experience with performing age hardening on a wide variety high temperature alloys including Inconel 718, 17-4 PH, and ASTM A297 HU Material.

Cincinnati Steel Treating has two induction hardening machines capable of heat treating small powder metallurgy gears, shafts, spindles, and brackets. CST can assist you in designing the right tooling for your application.

Our atmosphere pit furnaces enable us to vertically process long slender parts, thus minimizing distortion and reducing the straightening required.

CST has experienced professionals, including a degreed metallurgist, that can help answer questions about material selection, heat treating processes and metallurgical properties of materials.

Normalizing is used to improve the machinability, grain structure and mechanical properties in a wide variety of parts.

Cincinnati Steel Treating has a Gleason Press Quench capable of press quenching gears 26” in diameter and less. Press quenching is a very effective method of harden and tempering a ring gear with a minimum of distortion.

CST is a leader in stainless steel processing for the Midwest and beyond. This includes both 300 series (austenitic) and 400 series (martensitic) stainless steels.

Cincinnati Steel Treating has two presses capable of straightening both flat and round long parts to tolerances as low as 0.010” TIR. Our expertise in straightening is unmatched in the heat treating industry.

Cincinnati Steel Treating performs commercial stress relief operations on a wide variety of parts of different sizes, shapes, and conditions.

Cincinnati Steel Treating performs cold treatments and cryogenic treatments on parts on both a commercial basis and as part of an overall heat treatment process such as quench and temper.

Cincinnati Steel Treating routinely performs hardening and precision straightening operations on tool steel shear blades and knives. Consult one of our experts for determining the best way to heat treat your tool steel part.
