County Heat Treat

Let’s get into some further details on County Heat Treat’s operative capabilities:

Aluminum Treating – County Heat Treat’s aluminum treating department consists of four furnaces. Three are capable of solution treating and aging and one is solely for aging. Dimensions and heating capabilities for the solution and aging furnaces are as follows:

• 60″ x 60″ x 60″ 1100 degrees F maximum
• 64″ x 120″ x 62″ 1050 degrees F maximum
• 72″ x 102″ x 80″ 1450 degrees F maximum

Aging Furnace – Of note: County Heat Treat offers the choice of air blasting or water quenching and have full straightening capabilities. Furnace dimensions:

• 52″ X 72″ X 80″ 550 degrees F maximum

Shrink Fitting – The process of fitting a piece into a hole that is smaller than the piece itself. This is done by cooling the insert in liquid nitrogen, causing it to shrink slightly, and heating the other piece, causing it to expand. The parts are then assembled. When the assembled parts reach room temperature, they will be fit together.

Vacuum Hardening – County Heat Treat has four vacuum furnaces used for hardening tool steels, stainless steels, brazing and solution annealing. Their vacuum furnace capacity is able to meet the most demanding needs.

Straightening – Unfortunately, distortion is an unavoidable product of heat treating. This may be caused by any number of factors:

• Choice of steel relevant to the heat treatment required
• Severity of machining
• Defects in steel

Depending on each individual’s job requirements, County Heat Treat’s internal Straightening Department uses hot and cold straightening, peen hammering, or spot straightening to bring the product within precise finishing tolerance demands.

Nitriding – Operator’s load a plastic injection molding screw to be nitrided into one of County Heat Treat’s two nitriding furnaces. These nitriding furnaces are able to process parts up to 115 inches long and 38 inches in diameter, including stainless steel.

Neutral Hardening – Neutral hardening and gas carburizing of large pieces up to 60 inches long and 40 inches in diameter is offered. Material being treated is transferred from their internal atmosphere pit furnace to an oil quench bath.

Flame Hardening – Flame hardening is a long-used effective form of localized hardening. Fast and efficient, this method requires an experienced eye to run the job. County Heat Treat has over 100 years of combined experience to ensure maximum quality and customer satisfaction.

Inspection Department – At County Heat Treat, they are able to perform Rockwell and Brinell hardness testing, as well as micro hardness testing.

Brazing – In County Heat Treat’s fleet of four vacuum furnaces, they’re able to vacuum braze using copper or nickel compounds.

Cleaning (The Finishing Touch) – When desired, abrasive cleaning is performed in a variety of ways. Heavy-duty scale and discoloration are removed through sandblasting on a 72″ table blaster. Large volumes of small parts are tumble sandblasted. Other methods of cleaning include glass beading and aluminum oxide in sandblast cabinets.
