AHT's UltraGlow® case hardening processes have been in place since 1981 and have helped thousands of customers reap rich rewards as a result of improved product quality. UltraGlow® nitriding and nitrocarburizing are the ultimate surface treatments for low-to-high carbon steels, cast irons, stainless steels, powdered metals and any variation of tool steels.
Enhance Fatigue Strength and Save Money!
Due to increased compressive stresses at the part surface, fatigue strength is improved five to ten times its typical "non-treated" life, dependent on the material and part design. Studies have shown fatigue strength is improved without distortion as compared to other surface treatments, saving customers money on fewer operations.
Improve Corrosion Resistance!
UltraGlow's® case hardening processes can create a controlled white layer or compound zone which will improve a parts susceptibility to corrode or rust. This nitrogen enriched layer helps combat the elements and keep your parts looking fresh.
Excellent Abrasion Resistance!
With UltraGlow®, surface lubricity can be enhanced tenfold. UltraGlow® nitriding will improve the overall wear and tear of moving parts within another assembly. Such results can save customers significant $$$ and time can be spent elsewhere.
Be Lean and Green
UltraGlow® is an environmentally-friendly application. No toxic salts or gases are used within the manufacturing process. Therefore, it's a safe and clean process that will be around for a lifetime.
