We wish to produce a 1050 steel that has a tensile strength of at least 175,000 psi and a reduction in area of at least 50%.
(a) Recommend a heat treatment, including appropriate temperatures, that permits this to be achieved. Determine the Brinell hardness number, % elongation, and yield strength that are obtained by this heat treatment. (See Figure 13-9)
(b) What yield and tensile strengths would be obtained in a 1080 steel by the same heat treatment? (See Figure 12-27)
(c) What yield strength, tensile strength, and % elongation would be obtained in the 1050 steel if it were annealed? (See Figure 13-4)
