Galling Definition: What is It and How to Prevent It

The galling definition is an interaction (usually negative) between two materials as they slide past each other. It is also known as cold welding which occurs frequently in mating threads of similar materials and surface conditions. Stainless steel fasteners are the most prone to galling but can also occur with aluminum and titanium as well.

Prevention of galling simply involves changing the surface condition of one of the mating components. If dealing with aluminum, changing the alloy of one of the components is sometimes enough. Hardening to create a difference in the mating surfaces is another option. Lubricants are also good deterrents of galling.

However, there are several ways in which you can prevent or minimize galling. Check out the infographic below for those solutions.

How to Prevent Galling

Galling Prevention

Galling is the seizing or abrading of threads due to rubbing over time. Often different kinds of fasteners, such as those  made of stainless steel, aluminum and titanium are most likely to be subject to galling when tightened.  While it is important to know how to recognize and stop galling once it occurs, what is even more important during the manufacturing process is the initial prevention. If the correct steps are taken from the beginning, you may lower the risk of galling from the get go. (more…)
