I would assume CF is the same as CR as the alloy properties for both
listed on their website are the same. 1018 shuld be 1018, and the
only difference should be its temper perhaps, I really don;t know.
All the CRS I have ever seen has always been called either CRS or 1018
period, andits always had nice squared edges not rounded anywhere, and
a smooth or pretty smooth and scale free usually somewhat shiney
surface finish unlike HRS which is usually ronded n the edges somewhat
and has mill scale.

Unless this 1018 on the link I came up with at online metals is ground
to a closer tolerance perhaps.
