There's a boatload of that type of spec sheet there, Butch. Actually, many manufacturers offer pretty much the same type of array of info on their products. "crucibleservice.com" is loaded, for one. Check it out, you can spend days reading spec sheets.
The amount of information available to us is staggering if we take the time to seek it out. The internet has changed everything. For instance, on this one I typed "A8 tool steel" into Google and that was the fourth or fifth link.
Butch, whatever your chosen steels are, visit a couple of the manufacturers and copy out either the links or the data sheets. Learning about steels you don't use still has value because it teaches you what the various alloying elements do to not only the steel characteristics but how they affect heat treat. I keep printouts right in the front of my HT notebook.
How fast we learn is not as important as that we keep learning, IMO. He who wants to learn only enough to get by will fall by the wayside eventually as people learn his self-imposed limitations. It's one thing for a new maker not to know this stuff yet, but another for someone with 5 years to display a lack of desire to have learned. People notice that.
