into flat strips, which are further finished by cold rolling into what is known as cold-rolled flat steel, which is the raw material of an immense number of stamped and formed articles which are substituted for castings and forgings, and in which steel has become the substitute for brass and copper. A by-product of steel wire manufacture is sulphate of iron, which has many uses in the arts, as well as in the purification of city water supplies. The Com- pany also smelts zinc ores, obtaining as products commercial spelter, used mainly for galvanizing wire, sheets and tubing, and sulphuric acid, which is indispensable in the process of manufacture of the three principal classes of steel pro- ductions just mentioned; also muriatic acid, which is used for a similar purpose, and zinc oxide, one of the most important pigments in the paint industry. The company has a capital stock of $90,000,000, divided into $40,000,000 preferred and $50,000,000 common. BRAEBURN STEEL COMPANY The works of this Company are at Braeburn, Pa. The Company manufactures high-speed steel and other cruci- ble grades; also alloy steel of many kinds. The Company has been producing crucible steels since 1897, and electric furnace steel since 1916. It has two crucible melting fur- naces—one 24-pot and one 36-pot. It also has two 6-ton Heroult melting furnaces in which alloy steels of various kinds are manufactured. This Company is a Pennsyl- vania Corporation with an authorized capital of $400,000. CARBON STEEL COMPANY The Carbon Steel Company, whose plant is at the foot of Thirty-Second Street, Pittsburgh, has for many years specialized on alloy steels and special analysis steels. I was one of the first concerns in this country to roll steel bars for the Allied armies, as it received, direct from one of the Allied governments, shortly after the outbreak of the world war, a very large order for 4.5” shells. Later came orders for a large tonnage of shell steel in rolled bars. Steel
