What material is "10B21" ?

(OP)
Does anyone know what material "10B21" is and what a common cross reference may be ?

Thanks

RE: What material is "10B21" ?

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.

Dear Jonathan,

10B21 is a low carbon "Boron" bearing steel used for making cold headed bolts [Cold heading Quality].

RE: What material is "10B21" ?

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

RE: What material is "10B21" ?

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