During iron and steel production in our country, tons of scale is formed every year. The increase in the amount of iron and steel consumption in recent years has brought about a decrease in raw material resources, and therefore, the interest in scale, which contains high iron in its structure, has increased. The use of scale, which can be evaluated in different applications such as remelting or reduction, as a raw material creates a different area for recycling. In this study, the physical effects of steel scale used as an additive on acrylonitrile butadiene styrene (ABS) polymer matrix were investigated. Since the scale is separated by spraying over the steel billet, they come in different sizes. For this reason, steel scale powdered with a grinder was extruded to obtain a homogeneous mixture with ABS. The test samples in the dimensions suitable for the standards were molded in the injection machine and the density, abrasion, thermal distortion temperature (HDT), vicat softening temperature, melt flow index (MFI), moisture, hardness analyzes and microstructure examination of the composites were carried out. According to the test results; It was observed that the wear rate decreased with the addition of scale, but an increase in the rate of wear was observed with the increase in the scale rate. In addition, with the addition of scale, the density, vicat softening temperature, thermal distortion temperature value increased, while the moisture absorption and melt flow index values decreased.
