Hardening & Stress-Relieving & Stress Annealing

larger image
Our heat treating services harden, stress relieve, and stress anneal your materials to provide them with the desired mechanical properties required for their applications. We offer these services in our non-atmospheric furnaces for metal loads weighing up to 300,000 lbs. Materials are hardened by heating them in our furnaces to temperatures up to 2300°F and then rapidly cooling them in our quenching tanks. Air, oil, and water quenching services are offered to our customers.

Besides hardening the materials, we also provide stress-relieving services to remove the internal stress present in finished components caused by manufacturing or machining processes, such as forging, casting, and grinding. Stress annealing services are also provided to reduce the residual stress present in the materials, which are induced by either thermal cycling or work hardening. State-of-the-art instrumentation in our furnaces enable us to apply the required temperature for the exact period of time suited for each metal, and subsequently air cool them gradually. This reduces the residual stress in a wide range of materials including various ferrous and non-ferrous metals, including carbon steel, stainless steel, plus aluminum.
