Abstract
The objective of this research was to develop a new series of cost- effective chromium-free steels. The new steels are intended to be capable of adoption by a broad range of industry as a substitute for the chromium-containing 8600 and 4100 standard grades of heat- treated constructional alloy steels. Based upon several socioeconomic scenarios and their projected impacts on alloying element cost and availability in 1985, a computerized metallurgical design system was used to design two substitute steels for each of the standard grades. Both steels, a manganese-molybdenum substitute and a manganese-nickel-molybdenum substitute, are expected to provide heat-treat response and mechanical properties equivalent to the 8600 and 4100 steels. Small, experimental heats of the chromium- free replacement steels were prepared and their hardenability response and mechanical properties were evaluated and compared with the base-line 8620 steel.
