American Steel Treating Processes
Continuous Carburizing / Carbonitriding

The foundation of American Steel Treating is our inventory of two-row and three-row continuous pusher furnaces, more than any other commercial heat treater in North America. The furnaces process millions of highly engineered parts per year including many industry-setting features.The furnaces include multiple processes and several have robotic transfer of parts from process to process.

Some of our equipment includes:

• 3 Continuous two-row pusher furnaces
• 5 Continuous three-row pusher furnaces including a recently rebuilt Holcroft 3-row, 60-tray furnace
• 3 Continuous two-row pusher furnaces available for installation to accommodate future business

• All furnaces feature hot or cold oil quench

Batch Furnaces

American Steel Treating has a total of three batch lines, complete with charge cars, smart car, draw furnaces, and parts washers. Both plants have the option of hot and cold oil quench. Two of the batch furnaces have top cool atmosphere-controlled quench. Typically batch furnace processes include carburizing / carbonitriding and neutral hardening.

 

Features of our eight batch furnaces:

• Wash and draw
• Hot or cold oil quench
• Top cool atmosphere-controlled quench
Normalizing
• Smart Car System

Vacuum Furnaces

Feature of our three vacuum furnaces:

• The vacuum furnaces process high alloy steels to support the tool and die industry.
• Two bar nitrogen quench
• Hardening
• Bright Annealing
• Clean environment

Draw Furnaces

American Steel Treating has a large inventory of draw furnaces, both in-line with continuous pushers as well as stand-alone furnaces. Large volumes of parts requiring tempering are run through the continuous draw furnace.

Annealing / Stress Relieving

American Steel Treating has four Bell furnaces used for the annealing of coiled steel and to stress relieve after cold-forming processes. Large volume parts are run through the two continuous-belt annealing furnaces, which offer a shorter turnaround time. Parts requiring bright annealing are also annealed using the vacuum furnaces.

Shot Peen

Shot peening introduces a compressive residual stress to the surface of parts. This process helps to increase fatigue strength on components such as shafts, gears, differential and axle components. Another benefit of shot peen is its ability to prevent stress cracks around any drilled holes. American Steel Treating is one of the few companies that provide shot peening to customers.

Some features of shot peen:

• 7 Shot peen cells
• Long-term durability
• In-line process
• Offline process

Thermal De-Burr Technology

The thermal de-burr technology is unmatched in the shaft industry to ensure burrs are removed from internally drilled holes. This process works by vaporizing any metal residue or chips in drilled blind holes.

Some features of our thermal de-burr technology:

• 2 Thermal De-burr cells

Heat Flattening

American Steel Treating is the heat flattening supplier for the company who is the largest clutch plate assembler to the US truck market. The combination of using 50 tons of pressure to hold the plates flat while heat treating accomplishes flatness measurements not possible using other processes.

Some features of heat flattening:

• Quench and temper
• 50 tons of pressure to flatten
• Heat flattened on a stem
• Slip gauge verification of flatness

Finishing Operations

American Steel Treating employs multiple kinds of surface finishing, vibratory finishing and shot blasting. These applications are used for part cleaning and burr removal, as well as to help ensure the safety of those handling the parts. In addition to the blasting operations and equipment, American Steel Treating has multiple types of washers and rust prevention processes and equipment.
