The business became a limited liability company with Hadfield as Chairman and MD in 1889.

In 1913, the company assumed the name of “Hadfields”

He researched the effects of increasing manganese additions to carbon steel, discovering that when the Mn content reached 12-13% it offered remarkable resistance to wear.  It was used for machine parts, and steel helmets in the First World War.

He also developed Silicon steels with 1½% Si, and these were used in the top sides of the ships Mauretania and Lusitania, as a result of high tensile strength.

He researched many other aspects of steel metallurgy.

He presented 23 papers to the ISI, and many others to a variety of other audiences, and published two books.

He was elected an Honorary Member of 27 scientific and technical institutions at home and abroad.
