General services provided by the Matallurgical
Laboratory
are chemical and mechanical examinations for low carbon steel products. Moreover, our
laboratory
has also been certified for its testing standards which meet TIS 17025 standards issued by
the
Thai Industrial Standards Institute for its accreditations for Tension Test and Bend Test.
Tension Test
Tension test will provide the values of tensile strength , yield strength ,
percentage of
elongation and percentage of reduction area of specimens, we use Universal testing
machine
and�stress/strain rate control in accordance with specificed test standard.
Bend Test
The purpose of the test is to examine bend property of specimens by using mandrel
of which
the sizes would have to comply with standard specified at 180o. Followed the test,
the
specimens shall be visual checked to see cracked or any defects at the outside
surface of
the bent part.
Charpy Impact Test
The test is to check the impact properties of specimen at any temperatures
following
standard specification.The interested values are the absorb energy and %brittle
area.
Chemical Composition Test
The chemical analysis is checked by spark emission spectrometer method to
examine
a percentage of
the following elements : C, Si, Mn, P, S, Nb, V, Cr, Mo, Ni, Al, Cu and
N that
are effective to the steel properties of low carbon steel products.
