What is Super Duplex Steel and its Features

What is Super Duplex Steel and its Features

Super duplex stainless steel refers to duplex steel with PREN>40, containing 25% Cr and high molybdenum (>3.5%), high nitrogen (0.22%~0.30%), the main grades are UNS S32550 (UR52N+), S32750 (SAF 2507) And S32760 (Zeron 100) were developed by companies such as French CLI, Swedish SANDVIK and British MATER+PLATT.

Their deformed materials came out around 1990 and 1991, and entered the market in recent years. The composition of these three steels is similar, the difference is the content of tungsten and copper.

Outlining Super Duplex Stainless Steel

Super duplex stainless steel is differentiated from standard duplex grades by its significantly improved corrosion-resistant properties. It is a highly alloyed material with elevated concentrations of anti-corrosive elements such as chromium (Cr) and molybdenum (Mo). The primary super duplex stainless steel grade, S32750, comprises as much as 28.0% chromium, 3.5% molybdenum, and 8.0% nickel (Ni). These components impart exceptional resistance to corrosive agents, including acids, chlorides, and caustic solutions.

Generally, super duplex stainless steels build upon the established benefits of duplex grades with enhanced chemical stability. This makes it an ideal grade for fabricating critical components in the petrochemical sector, such as heat exchangers, boilers, and pressure vessel equipment.

Super Duplex Steel Features

- High weldability
- Very high resistance to pitting and crevice corrosion
- High resistance to general corrosion in acids
- Excellent resistance to erosion corrosion
- Excellent resistance to corrosion fatigue
- Good mechanical strength
- Excellent resistance to stress corrosion cracking (SCC) in chloride bearing - environments

Super Duplex Products

- Super Duplex Pipe
- Super Duplex Plate
- Super Duplex Round Bar
- Super Duplex Pipe Fittings
- Super Duplex Stainless Steel Flanges
- Super Duplex Bolts

Super Duplex Applications

Oil and gas industry equipment, Offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, injection and ballast water systems, Chemical process industries, heat exchangers, vessels, and piping, Desalination plants, high pressure RO plants and seawater piping, Mechanical and structural components, high strength, corrosion-resistant parts, Power industry FGD systems, utility and industrial scrubber systems, absorber towers, ducting, and piping.

Super Duplex Corrosion Resistance

The high chromium and molybdenum content of Super Duplex makes it extremely resistant to uniform corrosion by organic acids like formic and acetic acid. Super Duplex also provides excellent resistance to inorganic acids, especially those containing chlorides.

The pitting Resistance equivalent of Super Duplex, calculated by PREN = Cr + 3.3Mo + 16N, will exceed 40 in most material forms.

  Stainless Steel Boiler Tubes A boiler is a closed device that heats fluid (usually water) in. Don’t actually steam the gas. The heated or vaporized fluid leaves the boiler relying on Boiler tubes, cooking, and sanitation for use in different processes or heating applications such as water heating, central heating, power generation. There are two major types of tube Boiler tubes: water-tube Boiler tubes and fire-tube Boiler tubes. Philips Metal is one of the renowned manufacturer, exporter, stockist, stock holder and supplier of a qualitative range of   Stainless Steel 304 Boiler Tubes . These UNS S30400 Boiler Tubes are made up from heat resisting and low alloyed steels which can withstand the load at high pressure and temperature. Our SS 304 Boiler Tubes is used for parts of energy type equipment such as boilers, steam super-heaters, steam pipelines, etc. These WNR 1.4301 Boiler Tubes are also supplied as hot rolled or cold drawn.
