If you’re looking for a high-strength stainless steel product that can withstand extreme conditions, then Duplex S31803 Rings and Circle may be the right choice. These rings and circles are made from a blend of Chromium, Nickel, and Molybdenum with minimal nitrogen additives, making them highly resistant to corrosion and oxidation.
Properties of Duplex S31803 Rings and Circles:
While these Rings and Circles have commendable strength and durability, their high strength can make machining difficult. However, they respond well to cold working conditions and have excellent low-temperature properties. Their resistivity against various types of corrosion makes them suitable for use in environments that require protection against intergranular, crevice, and pitting corrosion.
Advantages of Duplex S31803 Rings and Circles:
One of the key advantages of duplex stainless steels is their exceptional strength, double that of austenitic stainless steels. Additionally, these rings and circles have a smooth finish, making them easy to fit into different assemblies. Our products use advanced machines to achieve a high surface finish and dimensional accuracy.
Applications of Duplex S31803 Rings and Circles:
These rings and circles are widely used in industrial applications such as oil and gas exploration, processing equipment, piping, tubing, and heat exchangers. They are also used in chemical processing equipment and environments with high chloride and aquatic surroundings.
