carburizing

• “Having determined what is required we now proceed to inquire into the question of carburizing, which is of vital importance.”

  The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel

• “* Briefly describe alternative carburizing agents (wood, charcoal, animal bone, leather, etc.) and mention other methods of case hardening.”

  Chapter 10

• “The utmost care should be used in the selection of pots for carburizing; they should be as free as possible from both scaling and warping.”

• “Case hardening boxes cast iron local or surface carburizing treatments for various steels”

  The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel

• “Although the advantages offered by the gas-fired furnace for carburizing have been generally recognized in the past from points of view as close temperature regulation, decreased attendance, and greater convenience, very little information has been published regarding the consumption of gas for this process.”
