What is Galling and Why is it a Problem for Stainless Steel?
Stainless steel is known for its durability and resistance to corrosion, but it is not impervious to wear and tear. One of the most common issues that can affect the performance of stainless steel components is galling.
Galling is a type of wear that occurs when two metal surfaces rub against each other and become stuck, causing small pieces of metal to break off. This can cause damage to the surface of the stainless steel, leading to reduced performance and potentially costly repairs.
Galling is particularly problematic in applications that involve high levels of friction, such as in valves, pumps, and fittings. It can also occur in applications where the stainless steel is exposed to high temperatures, pressure, or corrosive environments.
When galling occurs, the metal surface becomes rough and uneven, making it more susceptible to corrosion and further wear and tear. Over time, this can cause the stainless steel to weaken and eventually fail.
Examples of industries and applications prone to galling:
|Oil and gas
|Valves, pumps, couplings
|Propeller shafts, fittings, fasteners
|Conveyor systems, mixing equipment
“Galling is a common problem in the oil and gas industry, where it can cause equipment failure and downtime. It’s important to take preventative measures to protect stainless steel components from galling to avoid these costly consequences.”

|These coatings use a solid lubricant, such as molybdenum disulfide, to reduce friction between stainless steel parts.
|Highly effective at reducing galling and wear, can withstand high temperatures, and work well in dry environments.
|Electroless Nickel Coatings
|These coatings use a chemical reaction to adhere nickel to the stainless steel surface, forming a protective barrier against galling and corrosion.
|Durable and long-lasting, resistant to wear and tear and corrosion, and can be applied to complex shapes and surfaces.
|These coatings use a non-stick polymer, such as Teflon, to create a low-friction surface between stainless steel parts.
|Exceptionally low coefficient of friction, high resistance to wear and tear and chemicals, and can operate in both wet and dry environments.
|These coatings use a thin layer of ceramic material to provide a wear-resistant and durable surface for stainless steel parts.
|Can withstand high temperatures and harsh environments, resistant to corrosion and wear, and provide a hard and smooth surface for reduced friction and galling.
Where and When to Use Different Types of Coatings?
Depending on the application, certain types of anti-galling coatings may be more suitable than others. For example, dry lubricant coatings are ideal for applications that involve high temperatures or dry environments, while PTFE coatings are better suited for wet environments or applications that require a low coefficient of friction.
Before selecting a coating, it is important to consider the specific requirements of the application, including factors such as operating temperature, load bearing capacity, and the type of stainless steel being used. Consulting with a coating expert can help ensure that the appropriate coating is selected for the specific requirements of the application.
Factors to Consider When Choosing an Anti-Galling Coating for Stainless Steel
When selecting an anti-galling coating for your stainless steel components, it is important to consider several factors to ensure optimal performance and longevity.
Type of Stainless Steel
The type of stainless steel being used is a crucial factor to consider when choosing an anti-galling coating. Some coatings are specifically designed for certain types of stainless steel, while others may not be compatible. Ensure that the coating you select is suitable for the specific grade of stainless steel being used.
The operating environment is another important factor to consider. If the component will be exposed to harsh conditions, such as high temperatures, corrosive chemicals, or abrasive materials, a more durable and resistant coating may be required to ensure long-lasting protection against galling.
The specific application of the component should also be taken into consideration. If the component will be subjected to repeated or heavy loads, a coating with high load-carrying capacity and wear resistance may be necessary to prevent galling.
The cost of the anti-galling coating is also a key consideration. While high-quality coatings may come at a higher cost initially, they can often provide cost savings over time by reducing maintenance requirements and preventing costly repairs or replacements.
By taking these factors into account, you can select the most suitable anti-galling coating for your stainless steel components and ensure optimal performance and longevity.
How to Apply Anti-Galling Coatings to Stainless Steel
If you’re considering adding an anti-galling coating to your stainless steel components, it’s important to understand the proper application process to ensure optimal results. Below, we’ve provided step-by-step instructions for applying anti-galling coatings to your stainless steel products.
Step 1: Surface Preparation
The first step in applying an anti-galling coating to stainless steel is to properly prepare the surface.
