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%). The high corrosion resistance and excellent mechanical properties of duplex stainless steels can be attributed to their chemical composition and balanced (duplex) microstructure of approximately equal volume percentages of ferrite and austenite.

Possible precipitations in super duplex stainless steels within 25 40 minutes, while 2205 is ~1 hour and 2304 is ~8 hours for significant precipitations
While not as easily welded as austenitic steel grades such as stainless 316, low thermal expansion properties in duplex stainless steel means distortion and residual stress are reduced after welding. Duplex can be welded to carbon and low alloy steels as well as austenitic steels such as 316.
The low nickel content of the duplex grades also makes them price stable. What is duplex stainless steel? Duplex stainless steel grades have a ferritic-austenitic microstructure, with a phase balance of approximately 50% ferrite and 50% austenite.
Duplex stainless steel storage tanks are increasingly being used due to their long, low-maintenance service life. Surprisingly, they can also reduce initial costs for tank owners. The higher strength of duplex grades permits thinner walls requiring less steel.
alloying elements and good corrosion resistance. The caution with using duplex stainless steels is in understanding relative price compared to similar austenitic alloys and realistic availability. This paper reviews decisions to be made when considering a duplex stainless steel in todays market. Lean
Barriers to Using Duplex Steels. At the other end of the scale, there is a restriction on the low temperature use of duplex stainless steels compared to austenitic grades. Unlike austenitic steels duplex steels exhibit a ductile-brittle transition in the impact test. A typical test temperature is minus 46 deg C for offshore oil and gas applications.
Stainless steel - Wikipedia. In metallurgy, stainless steel, also known as inox steel or inox from French inoxydable, is a Stainless steel;s resistance to corrosion and staining, low maintenance, and The alloy is milled into coils, sheets, plates, bars, wire, and tubing to be used in . an austenitic structure in the steel, similar to nickel, but at a lower cost.

High corrosion-resistant and high strength UNS S32205 can withstand the brackish or salt water impact of a coastal flood surge. This quality along with long service life and low maintenance requirements led to the use of 2205 duplex stainless steel in pedestrian bridges.
Alloy 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.
Cold Work Hardening. 302HQ has the lowest work hardening rate of any of the common austenitic stainless steels. This results in a tensile strength increase of approximately 8MPa/%Ra (8MPa increase in tensile strength for each 1% reduction of area of cold work - this data from wire drawing).

304 Stainless Steel Sheet, is the most popular and economical of the stainless steels. 304 Stainless Sheet offers good corrosion resistance to many chemical corrodents as well as industrial atmospheres and marine environments. 304 Stainless Sheet may become slightly magnetic when worked and is not heat treatable.
Stainless steel, due to its superior corrosion resistance relative to most other metals, including steel and aluminum, becomes the cathode accelerating the corrosion of the anodic metal. An example is the corrosion of aluminum rivets fastening stainless steel sheets in contact with water.
Stainless Steel (Stainless Steel 304) Stainless steel is a steel alloy with a minimum of 10.5% chromium by mass and has a distinctly recognizable finish. The chromium content is the reason why it resists corrosion, heat damage, chemical damage, scaling, and maintains its high strength and high temperatures.
300 Series Stainless Steel Sheets Also known as Type 18-8 stainless, the 300 series stainless steel family features a number of variations, including 301, 303, 304, 310, 316, 317, and more. Despite the number of compositions, the common factor between them is that they generally (emphasis on the generally) consist of 18% chromium and 8% nickel.
Stainless Steel Grades and Families: Explained While stainless steels will share some characteristics, understanding the different types available is essential to finding the optimal traits and price point for your needs.
IV. Detailed Introduction to Stainless Steel. Ferritic steel; Low carbon chromium stainless steel with chromium more than 14%, chromium stainless steel with 27% and above chromium and any carbon content, and on the basis of the above ingredients add molybdenum, titanium, niobium, silicon, aluminum, tungsten, vanadium etc.
The letter L after a stainless steel type indicates low carbon (as in 304L). The carbon is kept to .03% or under to avoid carbide precipitation. Carbon in steel when heated to temperatures in what is called the critical range (800 degrees F to 1600 degrees F) precipitates out, combines with the chromium and gathers on the grain boundaries.

The impressive 99ft-tall horse head sculptures are completely clad in stainless sheets, providing the structures with an iconic shimmer associated with stainless steel. These majestic horses were built to honour Scotlands inland waterways and highlight the role horses played in this industrial and agricultural transformation.
Duplex stainless steels are characterized by high chromium content (20.125.4%) and low nickel content (1.47%) compared to austenitic grades. The low nickel content makes duplex grades more price stable. Molybdenum (0.34%) and nitrogen are added to improve corrosion resistance, while nitrogen also increases strength.
