The EN range of steel specifications was first introduced in 1941 as the War Emergency, British Standard Schedule BS970. With the assistance of the Technical Advisory Committee of the Special & Alloy Steels Committee the British Standards Institute published 58 specifications (EN1 to EN58). These steels covered a variety of types including carbon steels, alloy steels, case hardening steels, spring steels and stainless steels. The grades were arranged sequentially according to the chemical composition, starting with low carbon grades EN1, EN2 and EN3 working up to stainless steel grades EN56, EN57 and EN58. IN 1955 the BS970 EN range of steel specifications was revised to add further steel grades.
