Hadfields Limited of Hecla and East Hecla Sheffield, Yorkshire was a British manufacturer of special steels in particular manganese alloys (which were discovered by the founder's son and often known as Hadfield steel) and the manufacture of steel castings.
There was a very heavy involvement in the armaments industry, in the production of shells and armour plate steel.
In 1977 Hadfields became part of Tiny Rowland's Lonrho. The over-capacity of Britain's steel industry forced the closure of the Leeds Road plant in June 1981 and the East Hecla workforce was much reduced. Lonrho finally closed the last part of Hadfields in 1983 receiving compensation from GKN and the British Steel Corporation. Most of the site is now covered by Meadowhall Shopping Centre.
