Materials Selection Matters in Battle Against Corrosion

Whether specifying materials for instrumentation lines, hydraulic power, chemical injection, deluge systems, or other demanding applications, special attention should be given to managing corrosion. Just about every metal corrodes under certain conditions, but with proper materials selection the threat can be minimized.

At Swagelok Minnesota | North Dakota | Appleton, we help simplify the selection process with our deep understanding of factors that contribute to corrosion, as well as the special properties of materials that help fight it. As a supplier with a diligent focus on proper materials selection, we provide:

How to Control Corrosion

When you can visually identify corrosion and know where to look for it, risks to your fluid system can be minimized. Better yet, when engineers can anticipate corrosion and make the best choices, system integrity, longevity of assets, performance, and safety can all improve.

You can take these steps to reduce the impact of corrosion on your applications:

  • Identify types of corrosion— what it looks like, where it occurs, and why it happens
  • Minimize locations where crevice corrosion can occur
  • Avoid the contact of dissimilar metals, which can cause galvanic corrosion
  • Select materials resistant to corrosion
  • Specify everything from the supports and clamps to the tubing itself to reduce the potential for corrosion
  • Understand requirements and standards
  • Learn more through training and other resources

Identifying Corrosion

Corrosion is the physical degradation of a material due to interactions with its environment. It occurs when a metal atom is oxidized by a fluid, which leads to a loss of material in the metal surface. Corrosion reduces the surface's thickness and makes it more prone to mechanical failure.


Do You Have Rust?

Rust appears when you have carbon steel corrosion. This occurs when iron corrodes and forms iron oxide. Many other types of corrosion exist, however, that can threaten your application. Understanding the different types of corrosion can help in your material selection process.

Pitting Corrosion vs Crevice Corrosion

Read this article to gain a better understanding of two forms of localized corrosion in stainless steel: pitting and crevice corrosion. Swagelok experts cover topics such as:

  • What is pitting corrosion?
  • What is crevice corrosion?
  • Tips to prevent corrosion.


Avoid Galvanic Corrosion

Galvanic corrosion can occur when a metal comes in contact with a dissimilar metal. For example, when copper and steal components are threaded together. 

You can determine the compatibility of metals by using the the Anodic Index. This chart shows which materials are more noble, which means it is less susceptible to corrosion.
