Duplex steel S31803 tubes are one of the world’s most popular and widely used alloys. They are known for their superior strength, durability, and corrosion resistance. Duplex steel S31803 is duplex stainless steel with 25% chromium and 7% nickel content. It has a high strength-to-weight ratio and excellent corrosion resistance properties compared to austenitic stainless steels such as 304L and 316L. Duplex steel S31803 Tubes has outstanding pitting resistance thanks to its low carbon content, which helps prevent pitting corrosion.
Types of Duplex Steel S31803 Tubes
Tubes come in two forms, seamless and welded. Seamless tubes are made without welding, while welded tubes feature a weld seam along the length of the tube. Both types have advantages depending on your application needs however, seamless tubes are more widely used due to their higher strength to weight ratio and ability to withstand higher temperatures than welded tubes.
Benefits of Duplex Steel S31803 Tubes
ASTM A789 Duplex Steel S32205 Tubes offer many benefits over other types of metal tubing. They have superior corrosion resistance, which makes them ideal for use in corrosive environments like wastewater treatment plants or marine applications where exposure to saltwater also has excellent temperature resistance, making them suitable for use in high-temperature applications such as petrochemical plants or power generation facilities. They have exceptional fatigue resistance, which means they can withstand repeated cycles of stress without failing prematurely or excessively wearing out over time.
Applications of Duplex Steel S31803 Tubes
Due to their superior strength-to-weight ratio and corrosion resistance properties, tubes are commonly used in industries such as oil & gas production, food processing & packaging equipment manufacturing, automotive manufacturing & fabrication, wastewater treatment plants & marine structures, petrochemical plants & power generation facilities, chemical processing equipment manufacturing & construction projects requiring high strength materials with excellent corrosion resistance properties at elevated temperatures.
