Use of Alloy Steels in Iron- and Steel-Mill Equipment

Substituting alloy steels for the ordinary carbon steels in its mill equipment is the practice of the Central Alloy Steel Corporation when occasion arises to make a change. Elimination of breakdowns and costly repairs is claimed to be furthered by certain uses of the alloys. A gradual building up of the alloy-steel equipment is taking place. Producing alloy steel itself, the initial cost is low. There are three requirements which permit the substitution of alloy steels: (1) Increase of the physical properties of strength, ductility, and toughness. (2) The ability to withstand wear and abrasion. (3) Resistance to corrosion.
