Corrosion of 15-5PH H1025 stainless steel due to environmental conditions

A simple corrosion experiment was conducted to simulate the effects of stray current and salt water environmental conditions of 15-5PH H1025 stainless steel, which is a common material used on aircraft. Pieces of non-corroded 15-5PH H1025 stainless steel were immersed in 71 °C tap water without current, 71 °C tap water with current, and deionized water with current. It was determined that with time, the condition of 71 °C tap water with current formed corrosion pits on this material. It is always important that during the materials selection design of a product, all aspects, including environmental conditions that may potentially surround the product, should be considered.
