Ian, one other thing I would recommend is mark your steel or alloy materials so that you know whats what, I use paint which is a pretty standard way of doing it, however as far as I'm aware there is no standard colour range used? so just used whatever I had and made a "chart" A dab of colour on the end of the bar is all thats needed
Where I worked all Silver steel and gauge plate were marked so but the store man. colour was blue so I use the same for this.

My "Chart" !!!
