Machine OEM needs help with corrosion
Machine OEM needs help with corrosion
(OP)
My company builds machines for processing granite countertops. We are experts in machine design and not corrosion. I'm trying to establish a water specification so our customers don't accidentally cause excessive corrosion. I'm familiar with the Ryznar index but don't claim to be very keen with it. The machines operate in a very wet environment (like a car wash) with only water - no additives. We use very good paint. In some isolated cases the machines experience excessive corrosion (maybe 5% of the time). We build the machines out of painted steel, aluminum, and stainless. What would be an acceptable pH range to minimize corrosion of these materials? I've been told 7.8-8.2. Is that correct?
