Sulfuric acid is a commonly used chemical in the processing sector. Its corrosive effect on service material varies significantly, based on contaminants, temperature and water concentration. It is a problem with micro process equipments with thin walls. These equipments are usually joined by diffusion bonding that may affect material’s properties due to high temperatures and … Continue reading Hastelloy grades for sulfuric acid applications at different temperatures

While Monel 400 offers superior resistance to SCC in aerated acid, it is not adequate to prevent damage. Monel K500 and 400 grades are exposed to corrosive conditions in vapor phase of hydrofluoric acid in the presence of oxygen. Studies emphasize the need to eliminate air in the vapor phase above the acid. As HF … Continue reading Which alloy should be used in oil refinery processes for better performance
