Vol. XI February, 1906 No. 2 THE INDUSTRIAL FUTURE OF SPECIAL STEELS * By LEON GUILLET HpHE recent industry of special steels was for a long timeâ ** satisfied with creating at random many types of specialsteels, varying greatly and which a rapid selection has reduced toa few well defined compositions. At the present time, when the modern theories have madepossible the study of these complex alloys, it seems interestingto review the industrial future of these various special steels. They may be classified in a general way as follows: 1. Ternary steels, composed of carbon, iron and a thirdconstituent introduced purposely. 2. Quaternary t steels, composed of iron, carbon and twoother constituents. At the present time the arts do not call for more complexedsteels. It is, of course, understood that a steel containing onlysome traces of elements always
