How to deal with dissimilar metals | Trailer/Body Builders

Trailer manufacturers know that when using two dissimilar metals, precautions need to be taken to prevent two-metal (galvanic) corrosion. That applies even to the design, which uses steel frames in the axle and coupler areas. So how does a manufacturer approach the problem? Jimmy Yglesias, who was active in the Technology and Maintenance Council's S.7 group and chaired the task force investigating

FAQ 1: Galvanic/Dissimilar Metal Corrosion

Stainless steel has an effective passive film so the available corrosion current able to be carried by charged atoms (ions) is quite low. If the behaviour of a copper/steel and a stainless steel/steel couple is compared, the copper/steel coupling is a more significant galvanic problem despite the similar potential separation of 0.35 volts.
