H RECEIVED 21 JAN 1918 We understand that Mr. Hall has confirmed our impression that the lower carbon of Brown Bayley's "Quick Step" steel has a decided advantage and has condemned in all cases steel with a carbon of over .9% for any strong structural work. where the metal is subject to great stress.
