The Mechanical and Physical Properties of the British Standard En Steels (B. S. 970 - 1955), Volume 2 focuses on the most commonly used range of steels in the United Kingdom - B.S. 970 En Steels. The publication first offers information on 3 percent nickel steel and 3 ½ percent nickel steel. Concerns focus on welding, machinability, hot working and heat treatment temperatures, physical properties, transformation characteristics, and hardenability. The text then explores 3 percent nickel-chromium steel, 1 ½ percent nickel-chromium-molybdenum steel, and 2 ½ percent nickel-chromium-molybdenum steel (medium carbon). The manuscript takes a look at 2 ½ percent nickel-chromium-molybdenum steel (high carbon) and 3 percent nickel-chromium-molybdenum steel. Topics include welding, machinability, hot working and heat treatment temperatures, continuous cooling transformation, hardenability, and physical properties. The text also ponders on 4 ¼ percent nickel-chromium steel (with or without molybdenum), 1 percent carbon-chromium steel, and carbon case-hardening steel. The publication is a dependable source material for readers interested in the mechanical and physical properties of steels.
