No allowance had been made in the 1941 edition for a possible insertion of further steel grades and the british standards institution considered that to have applied a high en number would have divorced the grades completely from steels of similar types.
En2a steel sheet.
The main advantage of cold drawn steel is that steel can be brought closer to the finished machine size providing reduces machining costs.
Excellent machinability and suitable for case hardening and electroplating.
En1a mild steel 230m07.
The alloy is suitable for low strength components requiring significant drawing operations during manufacture.

The column on the left shows some of the steel grades stocked by hillfoot while the middle columns show grades with similar chemistry and the two columns on the right display grades for potential substitution.

Bs s511 is an unalloyed heat treatable carbon steel available in sheet and strip.
En1a also known as bs 970 230m07 is bright mild steel noted for its low carbon content.
Premium grade free cutting steel used by repetition engineers for a wide variety of applications.
Another benefit of bright steel bars is a marked increase in physical strength over hot rolled bars of the same section.
In 1955 the bs970 en range of steel specifications was revised to add further steel grades.
