What's the chemical reaction between stainless steel and galvanized angle iron?
If your products are not immersed in the electrolyte (not put in wet or condensed water place), just hope galvanized plate itself does not corrode, consider using stainless steel connections, but to do so, and will happen between the stainless steel plate, stainless steel carburizing rust resistance damage lost the meaning of stainless steel. The reason why stainless steel is corroded at this time is called intergranular corrosion".
Our company specializes in the production of stainless steel kitchenware, my experience, stainless steel and ordinary steel welding or not in direct contact, in order to prevent the corrosion of stainless steel, not to prevent corrosion of steel.
If your product will come into contact with electrolyte or water, stainless steel will produce a galvanic cell with carbon steel, which will accelerate the corrosion rate of both sides (of course, the corrosion of galvanized steel will be much faster). At this point, corrosion is called electrochemical corrosion, and the reaction rate is faster.
