چکیده مقاله:
The grate plates are one of the pertaining components of the grate machine in the iron ore pellet industry, which
is made up of heat-resistant stainless steel. The work life of these grate plates affects the production rate and
quality of the pellets. The purpose of this study was to investigate the cause of this steel sensitization and the
effect of elements on its lifetime. To do this, the lattice plates used in Zarand steel pellet factory were used to
build these steel plates which are ۱.۴۸۳۷ DIN steel. Samples were examined by electron microscopy, X-ray
diffraction test and polarization test. The results indicated that there is no depletion chromium in this steel, but
the steel carbide's crack cause the sensitivity of steel to intergranular corrosion.
