The Economic Aspect of Geology To eliminate this objection, many of the Liberty engine builders adopted the use of heat-treated and cold-drawn alloy steel for their highly stressed parts. The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel The classifications are as follows: High-speed steel, alloy steel, tool or crucible steel, and high-carbon machinery steel. The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel For working on high carbon steel, a rod of the steel being welded must be employed and for alloy steels, such as nickel, manganese, vanadium, etc., special rods of suitable alloy composition are preferable. Oxy-Acetylene Welding and Cutting Electric, Forge and Thermit Welding together with related methods and materials used in metal working and the oxygen process for removal of carbon The term alloy steel, from the steel maker's point of view, refers largely to nickel and chromium steel or a combination of both. The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel It is next to impossible to give proper directions for the proper Page 77 annealing of alloy steel unless the composition is known to the operator. The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel It has been found that other metals, if added to well-made steel, produce definite improvements in certain directions, and these "alloy steels" have found much use in the last ten years.
