My 2 steels are both bright drawn
230M07 (EN1A) free cutting steel
070M20 (EN3A) normal mild steel (that is what it is called here) similar to 1020 (I think)
All these bluudy different numbers really tick me off.
Stainless I tend to use only 303 - free cutting.
Brass havent a clue (there must be 1000s of different brasses) I go to the Brass place the guys show me the off cut area and I choose what I want.
Aluminium I choose the aluminium with the red paint on this is the harder grade suitable for machining.
I always go to the same suppliers, have done for the past 15 years or so, they know me and I know them.
Nearly all the steel, stainless, brass, aluminium I buy as off cuts from the off cut areas
