The duplex stainless steels are considered resistant to stress corrosion cracking, they are not as resistant to this form of attack as ferritic stainless steels. However, the corrosion resistance of the least resistant duplex stainless steels is greater than that for the most commonly used grades of stainless steels, i.e. 304 and 316. Duplex stainless steels are also magnetic, a property that can be used to easily differentiate them from common austenitic grades of stainless.Pipefittings
Duplex stainless steel offers excellent resistant to corrosion and very high mechanical strength. The high corrosion resistance of duplex stainless steel ensures significantly more uptime than carbon steels and conventional stainless steels, while the mechanical strength allows for lighter constructions, more compact system design and less welding.
Duplex stainless steel pipe (DSS) is featured with structure of two phases ( and ) and has characteristics of both ferritic and austenitic stainless steel. It has good corrosion resistance and high strength. It is alloyed with 18%-28% Cr and 3%-10% Ni in the condition of low C.
Super Duplex from Special Piping Materials Super Duplex is a stainless steel mainly used in oil and gas applications. Super Duplex alloys are characterised by a high chromium and molybdenum content.
Duplex 2205 is a nitrogen enhanced duplex stainless steelthat was developed to combat common corrosion problems encountered with the 300 series stainless steels. Duplex describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless.
Duplex and super duplex can be considered as higher grade stainless steel pipes, and are available on the market in the same dimensional range of conventional A312 stainless steel pipes (size range covered by the ASME B36.19 specification).
duplex 2205 stainless steel pipe combination of ferrite and austenite is the most beneficial properties, has the very good resistance to chloride stress corrosion cracking, is made up of 21% chromium, 2.5% nitrogen and 4.5% molybdenum nickel alloy consisting of duplex stainless steel, it is the yield strength of austenitic stainless steel double, this feature enables designers when designing products lose weight, make this kind of alloy has the advantages of more than 316,317L.
Jiaxing MT stainless steel co.,ltd. is best Duplex Steel Tube, Duplex Steel Pipe and Stainless Steel Coiled Tubing supplier, we has good quality products & service from China.
The most used duplex stainless steels are the 2205 (22% Chromium, 5% Nickel) and the 2507 (25% Chromium, 7% Nickel); 2507 is known as super duplex due to its higher resistance to corrosion.
Most duplex stainless steels have an over alloyed filler. For example, 2205 uses 2209 and ZERON 100 uses ZERON 100X. These filler metals are nearly identical in chemistry to the base metal, except for an extra 2% nickel. The increased nickel content aides in forming the 50/50 mix of austenite and ferrite phases.
Our Duplex Stainless Steel Pipes, Duplex and Super Duplex products are of European origin, have recognised quality and the required traceability. A number of Inian & Brazilian companies have been Oshwin clients for years through our international sales network. Duplex Stainless Steel Pipes
Duplex stainless steel. Duplex stainless steels have a mixed microstructure of austenite and ferrite, the aim usually being to produce a 50/50 mix, although in commercial alloys the ratio may be 40/60. They are characterized by high chromium (1932%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels.
2205 is the most widely used duplex (ferritic/austenitic) stainless steel grade. It finds applications due to both excellent corrosion resistance and high strength. The standard duplex S31803 composition has over the years been refined by many steel suppliers, and the resulting restricted composition range was endorsed as UNS S32205 in 1996.
Duplex Stainless Steel ASTM A182 F51 Weldolet, 12 x 3 inch Sockolet, Schedule 80 Pipe Fittings and MSS SP 97 Olet with full specification in abundant stock. It is a duplex stainless steel reinforced branch connection fittings. It is more safe and reliable than traditional branch connect fittings such as reducing tee.
Duplex Stainless Steels have roughly twice the yield strength of their counterpart austenitic grades. This allows equipment designers to use thinner gauge material for vessel construction!
Duplex describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless. The structure of 2205 duplex stainless steel consists of austenite pools surrounded by a continuous ferrite phase. In the annealed condition, 2205 contains approximately 40-50% ferrite. Often referred to as the work horse grade, 2205 is the most widely used grade in the duplex family of stainless steels.
Our commitment to quality service and construction of our super duplex stainless steel pipes is validated by our acceptance on most major Authorized Manufacturers Lists (AMLs). Specifications of super duplex welded pipe produced are A790, A928, and A999. There are some pipe sizes that are available from our inventory.

The 2205 grade steel is one of the most widely used ferritic and austenitic duplex stainless steel. The standard of this grade of steel has been refined over the years creating a versatile and strong product. It is has an excellent corrosion resistance (including in seawater), it is weldable by all standard methods, and has a high heat resistance.
SAF 2507 is a registered trademark for Sandvik. This is a Duplex alloy stainless steel designed to feature high strength, resistance to pitting, stress corrosion cracking, erosion corrosion and corrosion fatigue, crevice corrosion and strong weldability.
Dual-phase or duplex stainless steel whose grain structure is ferritic and austenitic. Applications Alloy S31803 and Alloy S32205 Stainless Steel is used most often in heat exchangers, marine construction, oil and gas industry, chemical processing.
Duplex Stainless Steel Grades. Duplex stainless steels contain a mixture of austenite and ferrite in their structure, and exhibit characteristics of both phases with higher strength and ductility. Nitrogen is added to the second generation duplex alloys and provides strength and improved weldability.
Duplex Grades. Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. Duplex stainless steel plate contains relatively high levels of chromium (between 18% and 28%) and low to moderate amounts of nickel (between 1.5% and 8%).

Duplex stainless steels are called duplex because they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel. The picture shows the yellow austenitic phase as islands surrounded by the blue ferritic phase. When duplex stainless steel is melted it solidifies from the liquid phase to a , duplex stainless steel pipe
