Types of Super Duplex Stainless Steel Tubes
There are two main types of super duplex stainless steel tubes: welded and seamless. Welded tubes are made by welding two pieces of metal together, while seamless tubes are made from a single piece of metal that is heated and then rolled into shape.
Welded super duplex stainless steel tubes are more cost-effective than seamless ones because they require less material to produce. However, they have a lower tolerance for pressure and temperature changes than seamless tubes. Seamless super duplex stainless steel tubes have a higher tolerance for pressure and temperature changes but are more expensive to produce.

However, they have a lower tolerance for pressure and temperature changes than seamless tubes. Seamless super duplex stainless steel tubes have a higher tolerance for pressure and temperature changes but are more expensive to produce.
Standard Super Duplex Tubes
Standard super duplex tubes are made from a combination of 22% chromium, 5-6% nickel, 3% molybdenum, and trace amounts of nitrogen. This composition gives these tubes excellent resistance to pitting and crevice corrosion in chloride-containing environments.
These tubes also have high mechanical strength and good ductility, making them suitable for use in high-pressure applications such as offshore drilling platforms and chemical processing plants.
These tubes also have high mechanical strength and good ductility, making them suitable for use in high-pressure applications such as offshore drilling platforms and chemical processing plants.
Super Duplex Lean Grade Tubes
Super duplex lean grade tubes have a lower alloy content than standard super duplex tubes. They typically contain 21-23% chromium, 1.5-2.5% nickel, 0.3-0.6% molybdenum, and trace amounts of nitrogen.
Despite their lower alloy content, these tubes still offer good corrosion resistance in chloride-containing environments. They are also more cost-effective than standard super duplex tubes while still providing good mechanical strength.
Super Duplex Hyper Grade Tubes
Super duplex hyper grade tubes are designed for use in highly corrosive environments such as seawater or acidic solutions. They typically contain higher levels of chromium (25-26%), nickel (7%), molybdenum (4%), and nitrogen (0.3%).
These tubes offer superior corrosion resistance compared to standard super duplex or lean grade tubes. They are also highly resistant to stress corrosion cracking and erosion-corrosion, making them ideal for use in offshore oil rigs, desalination plants, and chemical processing facilities.
Super Duplex Super Hyper Tubes
Super duplex super hyper tubes are the most advanced type of super duplex tubing available today. These tubes have a unique composition that includes 25-26% chromium, 7-8% nickel, 4% molybdenum, and 0.3% nitrogen.
In addition to their exceptional corrosion resistance properties, these tubes also offer superior mechanical strength and fatigue resistance. They are designed for use in extreme environments where other types of tubing would fail.
SAF 2507 Super Duplex Tube
SAF 2507 is a super duplex tube that contains 25% chromium, 4% molybdenum, and 7% nickel. This alloy has excellent resistance to pitting and crevice corrosion in chloride-containing environments. The yield strength of SAF 2507 is around twice that of standard austenitic stainless steels.
Zeron 100 Super Duplex Tube
Zeron 100 is a super duplex tube that contains 25% chromium, 7% nickel, and 3.5% molybdenum with additions of copper and tungsten. This alloy has excellent resistance to localized corrosion such as pitting and crevice corrosion in aggressive environments containing chlorides or hydrogen sulfide.
Ferrinox®️255 SD50 Super Duplex Tube
Ferrinox®️255 SD50 is a super duplex tube that contains high levels of chromium (25%), molybdenum (6%), nitrogen (0.3%), and copper (1%). This alloy offers superior resistance to both uniform and localized corrosion in harsh environments.
LDX2101 Super Duplex Tube
LDX2101 is a lean duplex tube that contains low levels of nickel (less than 5%) but high levels of chromium (21-22%) and molybdenum (0.3-0.35%). This alloy offers good strength, excellent formability, and weldability while providing superior resistance to stress corrosion cracking.
Standards of Super Duplex Stainless Steel Tubes
The most common standards used for super duplex stainless steel tubes include ASTM A789, ASTM A790, and EN 10216-5.
ASTM A789 is the standard specification for welded ferritic/austenitic stainless steel tubing for general service. It covers grades such as UNS S31803 (Duplex 2205) and UNS S32750 (Super Duplex 2507). This standard specifies the requirements for straight-seam or spiral-seam welded tubing with wall thicknesses up to 0.75 inches inclusive.
ASTM A790 is the standard specification for seamless and welded ferritic/austenitic stainless steel pipe. It covers grades such as UNS S31803 (Duplex 2205) and UNS S32750 (Super Duplex 2507). This standard specifies the requirements for straight-seam or spiral-seam welded tubing with wall thicknesses up to 0.75 inches inclusive.
EN 10216-5 is the European standard for seamless steel tubes for pressure purposes. It covers grades such as X2CrNiMoN22-5-3 (1.4462) and X2CrNiMoCuWN25-7-4 (1.4501). This standard specifies the requirements for non-alloy and alloy steel tubes with specified low temperature properties.
