What Is Corrosion Testing?

Corrosion testing is testing of various materials used in industrial applications to verify reliability and conformity of quality for the material.

Different corrosion tests reveal different weaknesses in material based on environmental factors which can range from temperature, physical and metallurgical situations, salt spray, and more.

Different Types of Corrosion Testing:

Immersion Testing
Immersion Testing, or, Alternate Immersion Testing is considered the most popular and simplest type of corrosion test. This versatile test is used to assess different materials that are subjected to particular conditions and can be personalized to meet specific needs regardless of application. In this test, the testing apparatus can expose the specimen to test solutions and then subject it to different physical or metallurgical situations, such as crevices and heat treatment.

Some Standardized Tests Available for Immersion Testing Include:

ASTM G31 Immersion Corrosion analysis applies to a wide range of conditions, allowing you to rapidly assess the corrosion rate of your materials and solutions.

Hot Wall Testing
Another test is the hot wall test, which is utilized to evaluate situations where metal vessels are hotter than bulk solutions. These are common in external heated vessels where corrosion is typically impacted by temperature. In this test, elevated temperatures signify high levels of corrosion activity.

Some Standardized Tests Available for Hot Wall Testing Include:

ASTM A262 Standard Practices for Detecting Susceptibility to Intergranular Attack in Austenitic Stainless Steels.

Salt Spray Testing
There is also a test known as salt spray. This technique is used to evaluate a coated sample's resistance to corrosion. This test produces an attack to coated specimens to measure suitability as a protective coating.

Some Standardized Tests Available for Salt Spray Testing Include:

ASTM B117 Salt Spray (Fog) Testing
ASTM D1193
ASTM B 368 Copper-Accelerated Acetic Acid Salt Spray, (CASS) Test
ASTM G85 Standard Practice for Mo\dified Salt Spray (Fog) Testing
ASTM G85 Annex A1 Acetic Acid-Salt Spray Test, Continuous
ASTM G85 Annex A2 Cyclic Acidified salt Fog Testing
ASTM G85 Annex A3 Acidified Synthetic Sea Water (Fog) Testing
ASTM G85 Annex A4 Salt/So2 Spray (Fog) Testing
ASTM G85 Annex A5 Dilute Electrolyte Cyclic Fog/Dry Test

Additional Testing
In addition to these, there are numerous other corrosion testing techniques available that help prevent loss due to corrosion. Please contact us today to learn more about our stress corrosion testing services and how we can accommodate your next project.

Why Do I Need Stress Corrosion Testing?

Controlling stress corrosion cracking is an important process for materials in the design and construction stages. By choosing a material that is not susceptible to SCC in the service environment, and by processing and fabricating it correctly, stress corrosion problems can be reduced or avoided.


Stress Corrosion Testing is useful for the Aerospace, Automotive, and Materials industries to assist in material selection, processing, and treatment options related to everyday corrosion stressors such as sweat, rain, humidity, or salt. Materials that are mainly tested for stress corrosion include:


What Materials Should Be Tested for Stress Corrosion?

Many materials are susceptible to stress corrosion cracking which can lead to damage, weakness, and failure for its intended applications. Different materials are affected by stress corrosion differently, which makes testing necessary for your material testing decisions.

Performing stress corrosion testing to assist in your materials decisions will ensure it has the intended strength, durability, coating, and reliability right for its end application. We have the experience and the extensive scope to test nearly any material for any application your project requires. Some materials commonly tested for corrosion are metals, polymers, and ceramics including:
