A carbon steel designated xxBxx is a Boron containing version of the regular steel, such as 1018 becomes 10B18 when Boron is added. Boron is added to improve hardenability and tweak oproperties.

Can anyone give me an idea on the machinability of 10B21? How does the Boron effect the machinability of 1021.

Boron would have no effect on machining, assuming you're machining the annealed part. Boron only affects the depth of hardening during quench.
