How to test the corrosion resistance of metal? - Salt spray test

The salt spray test is a standardized test method used to evaluate the corrosion resistance of stainless steel and other metals in a simulated marine environment. It involves exposing the material to a salt spray or mist, often with a solution of 5% sodium chloride, to assess its corrosion resistance.

The test duration can vary, but common testing periods are 24, 48, or 96 hours. After exposure, the samples are inspected for signs of corrosion, such as rust or pitting, to determine the material's resistance to salt-induced corrosion. The results of the salt spray test help in assessing the suitability of stainless steel for use in marine or corrosive environments and in comparing the corrosion resistance of different grades or surface treatments of stainless steel. It's important to note that the salt spray test is just one of many methods used to evaluate corrosion resistance, and the results should be considered in conjunction with other factors relevant to the specific application.

Andy Marine's marine hardware products will undergo 120 hours of salt spray testing and strict corrosion resistance testing to ensure the corrosion resistance of the products. If you want yacht accessories made of stainless steel, Andy Marine will be your best choice.
