Had an interesting query yesterday, a customer who ordered some prototype chemically etched stainless steel shims was asking if we knew anyone who could manufacture shims in hard and tempered carbon steel.  Now there was an easy one to solve, the customer thought you couldn’t etch metal which can rust.

Still amazes me the number of preconceptions surrounding the etching process that still exist, remember if you are unsure we are always happy to discuss your requirements.
