What metal is compatible with stainless steel? But almost any dissimilar metals can cause electrolysis. Chromium provides corrosion resistance to these alloys by forming a thin, adherent, corrosion-resistant oxide film on a clean (e.g., pickled, wire/rotary brushed, or ground) surface (of the alloy). That is 304 Stainless and it should not be affected by the bronze or brass it is in contact with but it may cause some increase in the corrosion in the bronze. So, for example, choosing zinc on zinc would have the lowest risk for corrosion. Generally speaking, brass can corrode if exposed to moisture for an extended period of time, which can range from a few weeks to months or even years in more extreme climates and environments. The most common form of steel corrosion is rust. In a galvanic couple, the metal higher in the series (or the smaller) represents the anode, and will corrode preferentially in the environment. As a general guideline, if the metals are half the length of the chart or more apart, the combination should be avoided. However, for any combination of dissimilar metals, the metal with the lower number will act as an anode and will corrode preferentially. Outfitting a sailboat to go cruising opens up a world of opportunities to waste your money. Presence of nearby concrete sealed with sodium acetate. As a designer, builder, engineer, or architect who works with exterior metals, you may have heard of the term galvanic corrosion (also known as bimetallic corrosion), or perhaps at the very least, are familiar with the concept of galvanized metals such as steel coated with a thin layer of zinc to prevent rust which employ a controlled form of galvanic corrosion to achieve their corrosion resistant properties.. Additionally, if you must use a combination of stainless steel and bronze components, it is essential to use a protective coating between the two to prevent corrosion.
