There is not universal color coding system, each metal foundry has
its own, or smaller shops make there own. I worked in a tool and die
shop a couple years ago that used white for d2, yellow for a2, and
there was one other I forget.

Basic question: When you buy steel alloys, how can you tell what
you have? Is there any kind of color coding? Sometimes rod has some
yellow or blue color on it. Is that meaningful?
Secondly, if you bought some stuff and don't use it all - do you
write the alloy on it with permanent marker? Or is there some way of
tell what you got? I don't mean telling stainless steel from
aluminum, but 12L14 from 1018 or drill rod.
How do you store it? Inside, of course, in a 'dry' basement that
is unheated and not all that dry. Do you keep the alloys separated?
Make up your own color coding? Do you wipe some oil on it to help
prevent surface rust? Looking for ideas!
