HOW TO MIX MATERIALS IN CORROSIVE ENVIRONMENTS
While often overlooked, selecting materials for a given application is one of the main design steps towards a safe and cost-efficient system. By selecting the best alloys and controlling corrosion, you can improve your application’s safety, life expectancy and performance.
That’s why Parker compiled this blog post detailing exactly what you need to know about mixing materials in corrosive environments.
Here’s what you can expect to learn about mixing materials:
Why you should use higher alloys for critical parts only. Parker often encounters customers experiencing corrosion problems. The most common solution in those cases is selecting new equipment made of a more corrosion-resistant material. However, higher-grade alloys should be used only in critical parts. Find out why.
How to define what’s critical. Corrosion-resistant alloys are more readily available than ever, but their outstanding properties are proportional to their price per kilo. In general, the higher-grade alloy is selected for the tube and a lower grade for the fitting or valve.
If size really matters. When there is a fissure in a material and the right amount of tensile stress, large thicknesses will not stop cracks propagating across the grain boundaries. It will just take a bit longer than thinner sections. Therefore, size does not matter.
What material isn't suitable for fittings. If a material is not deemed suitable for tubing, it should not be deemed as suitable for another component (after all, both parts will be exposed to exactly the same operating and environmental conditions). Find out which materials to avoid.
