THE EFFECT OF CURRENT AND VOLTAGE ON MECHANICAL PROPERTIES OF LOW CARBON STEEL PRODUCTS

This study presents an evaluation of the effects of electrical energy on the most important properties of low carbon steel such as yield strength, ultimate strength, hardness, and impact strength. These properties are the most important parameters of design and manufacturing of machine parts and structures. A36 is one of the low carbon steels which are widely used in different industries. The chemical composition of this steel includes carbon between0.17 and 0.2 (% wt).Present work focuses on the relationship between the change of mechanical properties of steel and electrical power passing through its products. Experiments show that increasing current or voltage passing through products made of this type of steel results in decreasing of their mechanical properties.
