 Shot
peening is a cold-working process in which a metal
part is bombarded by tiny balls of steel, cut-wire,
glass or ceramic shot. Although shot peening is often
confused with abrasive blasting, the two processes
have very different effects. Abrasive blasting is used
primarily to rid metals of corrosion and rust, while
shot peening is used to work-harden metal and to increase
its fatigue strength.
Although simple in concept, shot
peening has become quite technical in recent years.
Different shot types (grade, type, hardness, and shape),
varying impact angles, intensities, velocities, nozzle-diameters,
peening-times, the type of material and the surface
coverage can all affect the end-physical properties
of the peened metal.
Superior Shot Peening has over
50 years of experience, and have peened almost every
commercial metal known to man including exotic metals
such as hastaloy, titanium and zirconium. Our plant
is equipped with automatically controlled shot peening
machines that are capable of processing parts of different
shapes and sizes with consistent and unerring results.
Our mobile crews are equipped with similar, portable
machines and can do work almost anywhere in the world.
Whether done in-house or in the field, Superior
Shot Peening adheres to military specification MIL-S-13165C
when performing most shot peening services. However,
more stringent customer-specified standards are easily
accommodated. We are capable of handling custom shot
peening jobs of all types from the very large to the
very small and are experienced working under a variety
of difficult conditions.
We pride ourselves on our
superior quality control methods and are able to offer
a choice of several quality control tests to our customers.
Florescent dye penetrant per MIL-S-16561C, visible
dye check, almen strips and 10X magnification inspections
can be used individually or in combination per customer
specification. Our test equipment is calibrated to
military standard MIL-STD-45662A and is traceable to
the National Institute
of Standards and Technology.
A certificate of compliance is issued with each order.
