The corrosion of metals and alloys in acidic medium is a world-wide scientific problem as it affects the various processes like metallurgical, chemical and oil industries. Thus, an inhibition action of 1-N amido 3-methyl 4[2-methoxy] phenyl amino 1, 2-pyrazole on corrosion of steel in acidic medium has been investigated by weight loss method. Result obtained reveals that presence of these compounds reduces corrosion rate. Corrosion action increases with the increase in concentration of pyrazoles compounds. The increase in temperature leads to decrease in the inhibition efficiency of the compounds.
