The salt spray chamber test is a method of evaluating galvanic coatings and various anti-rust treatments. It is used to determine the resistance of metallic materials to corrosion.
In a salt spray chamber, products made of different materials and protected with diverse protective coatings and surface treatments are exposed to conditions that promote corrosion. By exposing them to such conditions for a pre-determined period of time, it is thus determined how the products would behave in extremely demanding natural environments over long periods of time and how efficient their protection against rust actually is.
Without such tests, it can still be predicted which factors will have the greatest impact on corrosion protection, however, it is difficult to foresee what would happen to door handles over many years. Therefore, we sent samples of Griffing’s front door stainless steel elements that are most exposed to external conditions for testing.
At Griffing, we have meticulously studied the processing of stainless steel for the production of door handles, door hooks and other door hardware, and following the example of the automotive industry we wished to scientifically assess the effects of various factors on the corrosion protection of products with the salt spray test.
Purpose of the test
The main purpose of the test was to check:
- the anti-corrosion effectiveness of the protective agents applied to the product,
- the impact of surface treatment on corrosion resistance,
- the correlation between the type of stainless steel and the degree of corrosion resistance.
