drill rod quality

hi experts,

i am about to make the first step to build my egraver/mill, and as i
have _no_ background in machining or mech. eng. i would ask some
dummy questions a few times.

it was hard to find where to but the "drill rods" for the guides,
finally i have found a company, that sells in small quantities, and
is willing to cut it to pieces for me.

this is the string they gave me about the material the rod is made
from:

1.4301
X5CrNi1810 (másutt: V2A)
304 <- they told me this is the US name/code for it.
KO 33

could someone tell me, if this rod will do with bronze bearings for
my first machine?

it is some kind of stainless steel, also called austenit (or contains
austenit)

sorry for the very beginner question.
