A Guide to Understanding Steel Grit and Steel Shot
The technique of sand blasting has provided many
different ways to clean up, strip, or even out
the surface of different materials. Although the
ancient mode of blasting- sand has now long been
banned for usage due to its dangerous silicosis,
there is still a huge range of much safer
substances that help to create a perfect finish-
be it the restoring of parts of a structure or
just basic refurbishing of smaller items.

Industries in the metal working business are the
principal users of cast steel shot and steel grit

• Steel mills

• Ferrous and Nonferrous Foundries

• Forge shops

• Metal Fabricators

Blast cleaning with the use of steel abrasives is
a vital and critical operation at various
different stages of the primary metal production.
Steel Grit and Steel Shot are two sand blast
medias that are most commonly used in todays
industries. These can be used for a huge variety
of applications to meet different goal
requirements. The following article will help you
build a strong understanding about both these
medias

What is Steel Grit?
Steel Grit is available in a variety of shapes
and sizes that will allow in administering a
variety of blast profiles for obtaining different
results. This type of grit is angular in nature
they way it has been created. This grit is ideal
for helping to remove the contaminants from the
surface of various products and it also creates a
last profile for new coating to adhere to. The
most common uses for steel grit are removing of
mill scale, removing different degrees of
coatings from the surface of products and a
typical grit sizes that are most commonly used
range between G25 G80. The larger the number of
the grits, the smaller will be the size of the
actual particle of blast media.

These smaller particles then create a smaller
blast profile on to the product on the other hand
the larger particles (the ones that have smaller
G numbers) will create a deeper blast profile. In
an addition to the depth of the blast profiles
the larger particles will show more effectiveness
in the removal of heavy amounts of paint while
the smaller lot of particles will be best suited
for removing contaminants on lighter surfaces.
The smaller particles with larger number like G80
grit will leave a 1 to 2 Mil profile and larger
particles like a G25 will leave deeper profiles
that range between 4 to 6 mils (this finding
stands true when, all the other blast equipment
settings remain the same).

scale of about 8.0 that is similar to the
hardness of the grit. This shot is used for a
vast range of processes where the primary use for
its application is referred to as shot surface
of the product being blasted by repeated striking
of the surface with steel shot. These repeated
striking makes the metal to compress that
increases its strength. Some of the most common
applications for this effect known as shot peen
the other areas of application that involve the
use of such shot i maximum levels of energy
transfer to effectively create a great sc
profile. This includes applications such as
concrete surface, rubber build up removal, epoxy
and adhesive removal.
What is Steel Shot?
This shot is available in a variety of different
sizes but is always designed in a round shape.
This is a hard type of abrasive with a mohs scale
of about 8.0 that is similar to the hardness of
the grit. This shot is used for a vast range of
processes where the primary use for its
application is referred to as shot peening. Shot
peening hahrdens the surface of the product being
blasted by repeated striking of the surface with
steel shot. These repeated striking makes the
metal to compress that increases its strength.

Just like the grit, these shot offer a lot of
uses before the needing replacement mostly
allowing about 150 to 200 cycles, depending upon
the application one is using these blasting
techniques for and assuming that the professional
uses the ideal blast media recovery equipment.
The sizing of the shots made from steel come in a
large variety of sizes that range between s 110
s 330. In contrast to the grits, here the larger
the number of the shot, the larger will be the
size of the steel shot, which means a shot of
size s 330 will be larger than s 110. The larger
shot are used for the removal of thicker coatings
and for heavier steel peening too
