Risi SDT98O is a high alloy dual phase ultra corrosion-resistant stainless steel strip. It has extremely high corrosion and cracking resistance. No painting or coating is required, thus minimizing maintenance workload. Widely used in pressure pipeline systems, biogas digesters, evaporators, road tankers, and other pressure vessels for seawater, chemicals, oil and gas processing.
