Erik Oberg's Heat-Treatment of Steel is a comprehensive treatise on the hardening, tempering, annealing, and case-hardening of steel, covering high-speed, high-carbon, alloy, and low-carbon varieties and the methods best suited to treating each type.
Oberg begins with the hardening of carbon steels, explaining how to heat the steel for hardening before moving on to quenching and tempering. Later chapters address the particular demands of high-speed and alloy steels, and the closing sections are given over to heat-treatment by the electric furnace, including the metallic-salt bath electric furnace and a range of other electric furnace types.
Highly recommended for modern metalwork enthusiasts, Heat-Treatment of Steel makes a fantastic addition to any collection of allied literature.
