EN1A is a very popular grade of low carbon-manganese free cutting steel, which
is most suitable for the manufacture of repetition turned components, such as nuts, bolts,
hydraulic fittings and studs, particularly where intricate drilling and machining operations
are involved.
It can be case-hardened, producing components with enhanced wear
resistance. En1a is also available as En1a leaded (En1aPb) for greater machinability. Swarf
will form in small chips to prevent machine blockage.
EN1aNL steel is a non-leaded Re-Sulphurised Free Machining Steel. This is a premium grade of
free cutting steel. It has excellent machinability. It is suitable for case hardening and
electroplating. We can provide you with free cutting steel both in the black and bright cold
drawn bar form.
