    the best steel type

    hello everyone,
    I am trying to make some tooling and seeing if some one can help me to choose the best kind of steel .
    I would like it to be very strong, I am also thinking of heat treating to make it hard, that way it will last a long time, this will be use for punch and dies.
    so far these are some steel types that I can think of (1018,1144,4140,and A36 ) if any one has a better idea I would greatly appreciated .

    Thank you

    Would depend on what you want to use the punches for and what size, 4140 is the only one in your list that you can heat treat, the others can be case hardened but this as I said would depend on what you want to punch through the 1018 and the A36 is mild steel, this is not normally used for punch and dies

    A2 would be my first choice for punches and dies. Depending on the shape, you might be better to buy ready made punches & dies from Dayton Progress. https://www.daytonlamina.com/punch-die They'll make any shape you want for reasonable prices and a very quick turnaround time. I have buying from them for at least 40 years. Then all you need to do is make the punch & die holders, normally made from 4140 or 4150.
