ABRASIVES
•
•
•
•
•
Copper Slag -An expendable synthetic
mineral abrasive which due to fast rates
works well for open nozzle blasting, various
grades are available.
Olivine - A natural mineral abrasive ideally
suited for cleaning of a brick masonry. A
number of grades are available to suit
applications.
Omni - A synthetic mineral abrasive which is
ideally suited to applications where a pale
coloured abrasive in aesthetically or
environmentally more desirable.
Steel - High carbon steel short and grit are
used in closed systems which employ
impeller wheels to propel the abrasive.
Available in different grades.
Garnet - A hard, durable, low-dusting natural
mineral abrasive which is capable of
achieving high coverage rates. Applications
include blasting of stainless steel and special
alloys.
•
•
•
Alumina - A very hard synthetic mineral
abrasive which is generally used in small
blast cabinets. Typically used for cleaning
non-ferrous components & stainless steel.
Vegetable Abrasives - Natural Organic
abrasives such as crushed olive stone or dried
corn cob have a gentle cleaning action suited
to turbine blades or die and mould cleaning.
Glass Bead - Very versatile material with a
large variety of applications including
deburring, deflashing, decarbonising, peening
and mould and die cleaning.

WIDE RANGE OF SPARES
ERVIN AMASTEEL PRODUCTS
• AMASTEEL Shot is actually a sphere-shaped form of steel
casting. Born of a process that was developed and patented
by John F. Ervin in 1939, shot is manufactured by pouring a
molten mixture of premium grade steel scrap and select
alloys through a series of water jets.
• On contact with the water, the molten metal is atomised,
forming round particles in a controlled range of sizes.
These particles then fall into a water tank, are dried,
screened by size, quenched and tempered in a unique heat
treatment process. This process assures ultimate control
over the microstructure and hardness of the product, prior
to a final screening.
• AMASTEEL shot has received more quality recognition
awards than any other abrasive manufacturer in the world.

Microstructure
The microstructure of cast steel shot shall be uniform martensite tempered to a degree consistent
with the hardness range, with fine well distributed carbides, if any.
Density
The density of cast steel shot shall be not less than 7 gm/cc.
General Appearance
The cast steel shot shall be as nearly spherical as commercially possible and no more than 20% of
the shot particles shall have objectionable defects.
Hardness
Ninety percent of the hardness checks performed on a representative sample shall fall within the
range of 390-510 VPN hardness number (40-50 HRC). (The hardness may be determined by any
of the various methods applicable to small sections such as Tukon Tester with VPN indenter, at
loads determined to provide a reliable conversion to Rockwell C.) (This is Ervin AMASTEEL 'S'
hardness designed for shot and grit
Mechanical Tests
Several designs of shot testing machines are available commercially for application to routine
procedures See SAE J445 for methods of checking uniformity of shipments of shot or grit to
determine relative fatigue life of different types of shot or grit.

Ervin AMASTEEL Special Hardness
L hardness - 90% minimum (55-60 HRC) 630 - 730 VPN
H hardness - 90% minimum (60 HRC minimum) 700 VPN minimum. AMASTEEL is also available in
other hardness ranges. For these requirements, the hardness of 90 % of the representative sample shall be
within a 100 point VPN range (6 point HRC).

Abrasives
Microstructure
The microstructure of the abrasive shall consist of martensite tempered to a degree consistent with the
hardness range The presence of free ferrite or free graphite is unsatisfactory.
Voids
No more than 10% of cast steel abrasive particles shall contain voids as determined at 10X magnification
A void must be greater than 10% of the area of the abrasive particle to be considered harmful.
Shrinkage
No more than 10% of cast steel abrasive particles shall contain shrinkage as deterwined at 10X
magnification A shrinkage area must be greater than 40% of the area of the abrasive particle to be
considered harmful.
Cracks
No more than 15% of cast steel shot particles, and no more than 40% of cast steel grit particles, shall
have cracks as determined at 10X magnification. A crack is a linear discontinuity whose length is greater
than 3 times its width and greater than 20% of the diameter
Particle Shape of Shot
When examined at 4X magnification, no more than 5% of the shot particles will have a length that is in
excess of twice the cross section.
