Stainless Steel Grits

Stainless Steel Grits General Specifications

Stainless Steel Grits- GRITTAL
Stainless Steel Grits- GRITTAL; is most important blasting abrasive used in cleaning of surface profiles,
development and improvement processes, on all aluminium parts, zamaks manufactured by pressure casting and
non non-metals, special alloys and manufacturing and casting of stainless steel parts. Moreover; is a
successfully applied roughening operation before coating.

GRITTAL
Sharp-edged alloy corrosion grit that spills with atomization process and hardened and grounded with heat
treatment.

When compared with mineral abrasives, GRITTAL grits have long life. Having a short period blasting, provides
rust-free, bright clean and free of dust surfaces. In both automatic (tribune ) and pressure systems can be
used.

STRUCTURE OF STEELS When calculated equivalents of Cr and Ni by examining chemical analysis
of Vulcan GRITTAL products, as can be understand in the following diagram easily, has been seen that these
products have austenitic structure. Austenitic structure materials have ductile structure and also have
feature as when hits and runs to be pressed, when pressed to be hardened. Moreover, austenitic structures
are not certainly fragile and only reduce their life by wearing. This specification also provides that
stainless steel balls produced by austenitic phase are been longer than long life.

According to the following diagram, can be easily visible in case of equivalent of Cr falls below 10 %
structure will be martensitic, in case of equivalent of Ni falls below 8 %, structure will be ferritic or
martensitic.
Martensit yapı östenit fazındaki çeliğin ani bir şekilde soğutulması sebebi ile elde edilmiş olan sert ve
kırılgan bir yapıdır. Dolayısı ile bu şekilde üretilmiş malzemeler aşırı kırılgan olup, uygulamadan sonra iz
bırakma ihtimali yüksek, düşük dayanımlı olmaları sebebi ile ömürleri kısa malzemelerdir. Ferrit, ise
Martensit kadar olmasada yine kırılgan bir yapıya sahip olup, çeliğin en yumuşak halidir. Bu yumuşak,
kırılgan ve düşük dayanımlı yapısı sayesinde iyi bir aşındırıcı olmadığı gibi kısa ömürlü bir malzemedir.

Martensitic structure is hard and re-short structure obtaining due to the sudden cooling of the austenite
phase of steel. Hence, the materials produced by this way are highly re-short, indentation probability are
high after application and short long life materials due to their low resistance. Ferrite also is not
although re-short structure as Martensite and is the softest state of steel. Thanks to their soft, re-short
and low resistance structure is not a good abrasive and short long life material.

FERRITE They are low carbon steel and the softest form of steel. Concurrently, have
re-short structure. Due to these features have low resistance and short long life.

MARTENSITIC Obtained by sudden cooling of austenite, they are supersaturated to carbon,
metastable phase and so hard and re-short structure. Causing low resistance and short long life due to this
highly re-short structures; they are not preferred to be used as abrasive materials.
