Characterization of wear and metallurgical properties for development of agricultural grade steel suitable in specific soil conditions

Extensive wear tests were carried out to establish the grades for their end applications in specific soil conditions. The wear pattern, as measured from weight loss, clearly established the superior performance of boron/chromium steel. In fact, compared to mild steel, high carbon, boron steel and chromium steel were 2.28, 2.50 and 2.53 times more wear resistant, respectively. The wear characterization gives a concrete direction to customers about the required quality, properties and grade of steel for agricultural tillage discs in their specific soil condition, which is cheaper and durable. The correlation of phase transformation, hardness and hardenability with wear resistance properties rendered the three composition of steel suitable for use in specific soil condition.
