Copper And Stainless Steel Compatibility
Based on their material compatibility with the substrates.
Copper and stainless steel compatibility. The information in this chart has been supplied by reputable sources and is to be used only as a guide in selecting equipment for appropriate chemical compatibility. Bituminous or zinc chromate primers can be used between copper and aluminum. 316l stainless steel chemical compatibility chart ver 10 jan 2020 industrials key to general chemical resistance all data based on 72 22 c unless noted explanation of footnotes 1 satisfactory to 120 f 48 c a excellent no effect c fair moderate effect not recommended. Similar metals are compatible.
When two dissimilar metals are directly connected together the lesser of the two metals experience galvanic corrosion which on a molecular level means that one metal readily gives up its electrons and one metal holds onto their electrons. If paints or coatings are used for isolation they must be compatible with both metals. Check the chemical compatibility of stainless steel with various chemicals solvents alcohols and other products. When dissimilar metals contact in the presence of an electrolyte a galvanic action occurs which causes one of the metals to corrode at a much faster than normal rate while the other corrodes more slowly if at all.
So the purified water quality will contain a lower percentage of. Sometimes it may have raised doubts about the use of brass accessories together with other metal pipes for the possible harmful effects on the installation. Stainless steel chemical compatibility chart. Iron and steel are generally not a problem unless their mass is similar or smaller than that of the copper.
Galvanic corrosion some times called dissimilar metal corrosion is the process by which the materials in contact with each other oxidizes or corrodes. Copper bronze a d e a b a e stainless steel 300 series a d e a a a e. This is because stainless steel and copper are actually dissimilar metals. Unfortunately ro water can be a nebulous term since ro is a reductive membrane separation process it will reduce the influent contaminants by whatever the rated reduction rate is of the membrane s at the operating tmp and flux rate.
Stainless can be susceptible to corrosion when chlorides are elevated. An effect that may occur is a corrosion known as galvanic corrosion which may happen with the contact of two dissimilar metals in the presence of. Dissimilar metals are not. Fasteners that are compatible with preservative treated lumber are stainless steel fasteners or hot dip galvanized nails manufactured.
