  1. @MattBower There are two different phase diagrams for steel. One is the carbon-iron equilibrium phase diagram and the other is the iron-iron carbide metastable phase diagram. The equilibrium diagram is of interest to metallurgical scientists, where the eutectiod is exactly 0.68% carbon at 738
  2. H13 makes wonderful hot work tools. Unlike Charlotte, I don't even try to forge, just machine the annealed stock and then heat treat to Rockwell C 50.

  5. Ron Hicks, H13 is used extensively in forge shops for high temperature tooling and retains hardness well even when heated to a dull red. Composition is 6% chrome and 1% moly. Tools made from H13 hold up even under fair severe abuse. H23, H24, H25 contain 10 to 18% tungsten. If your bar is one of these alloys, then it will hold hardness up to a bright red heat. The down side comes if you try to forge any of these alloys. They require temperature control that far exceeds a simple hand forge. The tools I have made from H13 have all been machined to size, no forging.
  6. canman, First, I have never actually built a gate (every time I start to think about it, the amount of metal involved ends the thought quickly), but I have read the CoSIRA book on fences and gates. From what I have found there, the individual pieces of the gate do not have to be that elaborate or difficult to forge. The major effort is in assembly, particularly for those that use forge-welded collars. If you can weld well enough that the welds don't have to be hidden, then your gate project can go very quickly. Now all you need is a design and a few template to make sure the pieces are forged to the correct size.
  7. Paige Price, Contactpaper shelf liners make a pretty good resist. Apply to the entire panel, avoiding bubbles, then cut away the area to be etched with a sharp knife.
