Hi Pat, folks.....

>>    Ask for W1 or W2 water-hardening tool steel. 

>     An amazingly good writeup and to add in another resouce for tool
>     steel is mscdirect.com page 1718 in the big book. Comes in 36"
>     lengths and VERY reasonable. 

    If you want a rod shape, the round stuff is commonly known as "drill
    rod"....... O-1 (ya quench in oil, or if you're me, tranny fluid--use
    ventilation, saftey glasses, etc) is the most common.....but W-1 is
    available, too...Standard length is 18 or 36".... 

    Rectangular or square stuff is known as "flat stock"......and comes
    in standard 18 and 36" lengths....O-1 and A-2 most commonly.... 

    This stuff is usually precision ground, and since flats take more
    work than rounds, the flat stock is more expensive... 

    Both are sold already annealed...... 

    Many sizes available in both....many Industrial Distributors stock
    it.... 

    My outfit, the day job that keeps getting in the way....does.... 

    Just a sidebar here....the industrial recommended quenching liquid
    for W-1 is a brine solution... 

    And heat treating high carbon steel, hardnening, quenching, and the
    tempering or draw, is a bit different in most cases than when you're
    doing the same to the jewelry metals... 

    If you know someone who's a gun nut, they probably have a Brownell's
    catalog....... There's a short section on the ABC's of heat treating
    high carbon steel.....conveniently next to their drill rod
    selection..... One of the cool things about the process is when you
    do the final tempering, ya can tell what you have by the color,
    pretty much....and, you can do some of it in a toaster oven or
    kitchen oven.... There's an absolutely vibrant purple you can
    get....it's only a surface thing, that almost wipes off with fine
    sandpaper...but think like amethyst.... 

    If you know a real gun *nut*....a tinkerer or smith, say, they might
    have one or all of the Brownell's "Gunsmithing Kinks" books.....much
    more info in there...
