What is Galling and How do you Prevent it?

By definition, galling 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. Galling is most common with stainless steel fasteners, 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.
