New Steel

Machine builders have always wanted a steel that had a soft core with a hard surface or "skin." Such a steel would furnish an enduring wearing surface and yet be easy to shape. It would be invaluable to makers of motor cars, typewriters, adding, sewing, knitting machines--wherever wearing parts are needed. Metallurgists have produced soft, shapable steels. They have devised hard steels which were expensive to "work." But not till last week did any one announce a steel with all the desiderata of the machine builder.

Metallurgists for the Jones & Laughlin Steel Corp. of Pittsburgh have devised this new steel, which they have named "Jalcase." It possesses a "triple combination of fast machining, casehardening and forging properties."
