This study concentrates on corrosion properties that expose to soil environment. The widespread properties of corrosion are important in further study based on corrosion of underground pipelines in Kubang Kerian, Kelantan, Malaysia. 124 of mild steel coupons used as sample was investigated by stimulating and analysing the physico-chemical characteristics of the soil environment. The soil parameters examined in the study are; pH (moderately acidic, neutral, and strongly alkaline), and moisture content (40%, 60% and 70%). The soil is sandy clay in natural. Corrosivity of the soil samples was evaluated using the AWWAC 105 numerical scale. A total summed index of 2 was obtained which indicates that the soil tested was mildly to non-corrosive. The result obtained show that corrosion rates increases with increasing of moisture content and pH value.
