Assessment of mechanical properties of mild steel drawn using vegetable fatty-based oils as lubricants

Abstract

A comparative assessment of the Mechanical Properties (Yield Stress, Yield Strain, Ultimate Stress, Breaking Stress, Breaking Strain, Percentage Elongation and Percentage Reduction in Area) of Mild Steel wires drawn using standard (Sodium Stearate Solution) and three Vegetable fatty oils (Palm Oil, Cotton Seed Oil and Shear Butter) was carried out. The results show that the Vegetable fatty oils produced wires with higher strain-hardening than those of the standard lubricant but with the same ductility and malleability. It also shows that Palm Oil is the best lubricant among the three Vegetable fatty oils considered. Significance Mild steel is the most common metal used in any production process and lubrication is a very important aspect of any
forming process. Fatty based oils are usually used as lubricants in this process. The work looks at the effects of vegetable fatty oils, as lubricants, on the mechanical properties of mild steel.
