HEAT TREATING
Century, LLC operates one of the most modern and technically equipped heat-treating facilities in the country. By utilizing state-of-the-art instrumentation and controls, and an unsurpassed quality assurance program, we can provide the metallurgical structure and consistency of hardness necessary for maximum performance of precision parts.
Deep Salt Bath
Century Specialties continues to lead the thermal processing industry with the modern installation of its long length hardening line custom engineered, designed, and built to accommodate parts fully immersed to 110" in length. This liquid molten salt bath hardening line is the largest of its kind for the quench and temper of tool steels, high speed steels and powder metallurgy. Experts in the hardening and straightening of long length tools, Century Sun continues to emerge as the leader for the thermal processing of specialized tooling within the heat treating industry.
Ion Nitriding
This is the high-tech advancement in nitride processing, through the use of vacuum technology, exacting computer controls and gas mixing techniques. A case hardening process dramatically increases the wear resistance of tools, while significantly improving corrosion resistance. The vacuum process not only leaves surfaces clean, but also minimizes dimensional distortions.
At specific temperatures and electrical voltage levels, nitrogen gases are ionized and impregnated into the compound layer as iron nitrides. The control of temperatures, voltage and amperage, and gas mixtures, work together to create the depth of penetration and degree of hardness optimal for the intended uses of the workplace.
Vacuum Hardening
Our high pressure quench vacuum furnaces incorporate thorough and uniform convection assisted heating along with directional cooling of up to twelve times atmospheric pressure. The results are excellent distortion control with superior quenching rates, which provide the highest quality vacuum heat treated products available in today’s marketplace.
Hardening, Carburizing, & Carbonitriding
Super Allcase® hardening line designed for neutral hardening, carburizing, or carbonitriding. Multiple tempering ovens accommodate all material requirements and hardness ranges.
Induction Hardening & Cryogenic Treating
Hardening services include a horizontal induction deep case long length up to 150" and vertical induction long length up to 70". Our cryogenic treating "cold chamber" can accommodate load sizes to 36" x 36" x 50" up to a 4,000 lb. and thermal processes to -300 °F.
