White Papers & Case Studies
-
With the variety of surface treatments available today, it can get confusing trying to decide which one is best for your application. Gas nitriding is becoming more and more popular since it is environmentally-friendly, while also offering significant benefits.
-
Advanced Heat Treat Corp. was approached by one of the premiere steel makers in the southeastern United States. The steel producer was having issues with corrosion in the hot working section of their mill. The high corrosion rate was attributed to two factors; heat and process water. Heat has been well documented as increasing corrosion in humid and/or wet environments.

In every major industry companies are taking notice of the positive effects that streamlining can have on their internal processes, and economic returns. Through these continuous improvement efforts, companies see cost reductions in categories such as turnaround time, reduction of defects, and elimination of waste, to name just a few. While these concepts are just getting a foothold in industries such as retail and medical, they have an established history in manufacturing. The heat treat industry, and specifically the ion/gas nitriding subset, is not an exception.
-
Learn how common metals, such as steels, are heated to high temperatures and the significant changes that occur at the atomic level.
-
Scot Clay
Discover the pros and cons of the selective heat treatment: induction hardening.
-
Mikel Woods
In this white paper learn about ion nitriding, also known as plasma nitriding, and the benefits it provides for parts. In particular, read about how ion nitriding improved the wear resistance for an automotive club hub housing piece.
-
Gary Sharp
Various heat treat methods are available to enhance wear resistance and provide surface hardening on long parts such as screws, shafts and rolls. Learn what the best method is for heat treating long parts and the longest part Advanced Heat Treat Corp. has ion nitrided.
-
Chad Clark
What materials can be nitrided? What temperature are parts nitrided? Learn the answers to these questions plus more.
Technical Papers
-
From 4140 to titanium to cast iron, view the typical hardness, compound zone and total and effective case depth.
-
From size capabilities to cost/quotes to logistics, Advanced Heat Treat Corp covers ion and nitriding FAQs.
-
The differences in mechanisms of nitrogen transfer between plasma (ion) nitriding and gas nitriding have various practical consequences. For example, gas nitriding increases the surface roughness of gray cast iron. Proper identification of the advantages and disadvantages of these two methods could significantly improve their use.
-
Ion nitriding can be used in many applications, but some are so unique that they can be called “the best” applications, where the competitive treatments such as salt bath and gas nitriding cannot easily duplicate the unique results of ion nitriding.
-

Plasma nitriding offers a way to significantly improve the surface properties of tool steel stamping dies, and is not limited by their size to its application, as are some alternative surface treatments.
-
E. Rolinski, T. Damirgi and G. Sharp
Wear, corrosion and fatigue properties are strongly dependent on surface quality and its modifications.[1] Thermochemical methods such as gas and plasma nitriding allow for enhancement of these properties in most severely loaded (mechanically and/or chemically) applications without causing any changes in dimensions of the treated objects.
