In the oil and gas sector, welded fabrications must resist very harsh operating environments where they may be subjected to high temperatures, pressures and corrosion. Therefore stainless steels such as 6 Moly and Duplex which have a high corrosion resistance – particularly to stress corrosion cracking - are becoming more common across the industry. However, these high performance materials can prove more difficult to work with, especially in terms of grinding.
