Duplex Steel is a type of stainless steel that has a two-phase microstructure consisting of both austenitic and ferritic grains. It offers excellent strength, corrosion resistance, and high durability. There are several grades of duplex steel, each with unique properties that make them suitable for specific applications. Here is a brief description of duplex steel products with grades
Duplex Steel Grade :
|
Stainless Steel Alloy Duplex 2205, UNS S32205 |
|
|
Duplex 2205 |
Duplex 2205, also known as UNS S32205, is a nitrogen-enhanced stainless steel. Users choose Duplex 2205 for its excellent corrosion resistance along with its high strength. It is important to note that Duplex 2205, offers much higher levels of corrosion resistance than most other austenitic stainless steels. |

Stainless Steel Alloy 2304, Duplex 2304 |
|
|
Duplex 2304 |
Duplex 2304, also called Alloy 2304, is a molybdenum-free duplex stainless steel. It has a structure that is a balance of ferritic and austenitic and is often used as a replacement for Alloys 304L and 316L. Some of Duplex 2304 stainless steel’s other properties include. |
|
Stainless Steel Alloy Duplex 2202, DX2202 |
|
|
Duplex 2202 |
Duplex 2202, or DX2202, is an austenitic-ferritic stainless steel. It offers users general resistance to corrosion that is comparable to Type 304L. Some of the other key characteristics of Duplex 2202 include. |
|
Stainless Steel Alloy 2507, Duplex 2507 |
|
|
Duplex 2507 |
Duplex 2507, is a commonly used super duplex stainless steel. Also sold as Alloy 2507, this alloy is used in situations where exceptional strength and corrosion resistance are in demand. |
|
Stainless Steel Alloy Zeron® 100, Super Duplex Stainless , Super Duplex |
|
|
Zeron® 100 |
Zeron® 100, which is also sold under the names Super Duplex Stainless and Super Duplex, is a highly alloyed stainless steel that is designed for use in difficult and aggressive environments. Because of its outstanding strength, Zeron 100 is known as a super duplex stainless steel. Originally created for applications that demand corrosion resistance to seawater in the North Sea, Zeron 100 is also perfect for other industries and applications. |
