How to etch steel plate with common products?
(OP)
I am working on a welding procedure and the welding expert said that we should prepare the test plates with the "Grain" of plate a certain direction.
One of the testing labs I work with told me to use a solution of HNO3 and 98% Ethanol but finding small amount required is becoming complicated.
Does any know of any products that I can get at the hardware or grocery store that can etch the steel enough to determine the direction the plate was rolled?
Best regards, David

Tap-out chemical remover for removing broken taps is essentially Nitric acid.
It is available in small quantities, but it is not cheap.

I could get a liter with a note on company letter head for the most part, good looks just doesn't go as far as it used to, but all I need as about 2mL.
Any way the materials lab is sending one of their guys out next week so I'm covered.
Thanks to all for you time.
