The method of inhibiting corrosion in a steel pipeline by a slurry comprising water as the vehicle for carrying a comminuted material which is reactive with oxygen, as for example, coal. Inhibition of corrosion is obtained by the addition to the slurry of pellets containing hexavalent chromate, which is released into the slurry in a controlled amount sufficient to inhibit corrosion but wherein the concentration of chromate is not so great that excessive amounts thereof are consumed by the slurry material.
