Choosing The Right Metallurgy For Your Heat Transfer Fluids
Which metals are compatible with heat transfer fluids? Well, the answer depends on the base chemistry of the heat transfer fluid in question. In the table below, we classify the compatibility of different metallurgies with different types of heat transfer fluids
304 Stainless Steel
316 Stainless Steel
* The susceptibility of aluminum to pitting corrosion is well documented. This depends on many system factors, such as chloride ion concentration, pH control and initial surface condition.
** Copper ions catalyzes an oxidation reaction that eventually leads to the formation of sludge. We recommend that you utilize a heat transfer fluid like Relatherm formulated with metal deactivators to mitigate this effect.
*** Compatibility rating applies only to inhibited glycols.
