The single biggest complaint about machining stainless bar
is its lack of consistency. Not true with CMQ®.
What is CMQ® anyway?
CMQ® (Consistent Machining Quality) is a unique, highperformance stainless steel that offers you the most consistent
and machinable solution available today. Bar to bar. Lot to
lot. Part to part.
Other Material
Why is CMQ® so good?
CMQ® is custom-produced by a select group of mills in strict
accordance to Castle’s exacting production specifications.
Consistency is achieved through careful process controls in all
aspects of manufacturing, from the melting practice to
chemistry control, from restricted
hardness to the annealing
practice. In turn, this eliminates
extra set-up time, rejected parts, the
need to replace tool inserts, and a host of
other productivity problems.

Poor Machinability
CMQ® eliminates
poor performing
data points and
dramatically
improves material
variability.

By improving consistency, Castle has created a proprietary
stainless that is far more predictable than the competition.
And that means no more surprises and a surefire way to
crank up your productivity, without having to change the way
you operate.
The CMQ® process manages
three key areas:
Grades
1. MELTING AND REFINING PRACTICE
1/4" through 6" rounds and 1/4"
The most modern equipment and refining techniques
(including ladle treatments) are used to offer excellent heat to
heat consistency, repeatability, and the correct composition,
shape and distribution of inclusions.

2. CHEMISTRY
availability to all markets.
Carbon, Manganese, Chrome, Sulfur, Nickel and Nitrogen, to
name a few, are all carefully controlled and significantly
restricted for consistent, high-performance materials this time
and every time.
Value
For virtually the same cost as ordinary stainless, CMQ® offers superior
value in total part cost.
3. MECHANICAL PROPERTIES
Hardness is a critical variable when it comes to consistency.
By optimizing the annealing practice and cold finishing
practice, CMQ®’s hardness and other mechanical properties
are restricted to achieve outstanding material structure.
