Details Facts on S32205 Duplex Stainless Steel Pipe

Why Duplex S32205 Pipes?


Duplex UNS S32205 pipes come in a wide range of thicknesses, specs, diameters, and shapes to suit the needs of the customer. These pipes are used extensively in many industries, including the food processing industry, because of their superior finishing, pinpoint accuracy, longevity, and resistance to corrosion. Rajendra Steel, one of the top suppliers and manufacturers, makes these pipes.


We guarantee that every one of our goods is made in accordance with the demands and specifications of our customers. So that our customers could readily utilize the pipes in specific applications, we sought to provide pipes of the highest quality and dependability. Our company is a well-known producer of pipes and offers the best prices to our clients. For stainless steel grade 2205, we present a grade comparison. The comparison of values of materials with comparable functional properties. From the original specs, exact S32205 Equivalent Material can be acquired.


Duplex Corrosion Resistance of UNS S32205 Duplex Stainless Steel Pipe


Excellent general corrosion resistance in most situations, superior to Grade 316 excellent resistance to localized corrosion, including pitting, crevice, and intergranular corrosion; the CPT of 2205 is typically at least 35 oC. At temperatures up to roughly 150oC, the grade is also resistant to chloride stress corrosion cracking (SCC). In circumstances where austenitic grades prematurely fail, grade 2205 frequently performs well. It can withstand seawater better than Grade 316.


S32205 Equivalent Material


Due to their numerous qualities, including good corrosion resistance and high tensile strength, duplex steel S32205 seamless pipes are employed in a variety of industries. Additionally, they are portable, simple to install, and able to withstand extreme conditions.


Two-phase, ferritic, and austenitic stainless steel alloyed with 22% chromium, 3% molybdenum, and 5–6% nickel is known as UNS S32205. It doubles the yield strength of typical austenitic grades and is the most popular grade of duplex stainless steel.


In the annealed state, the S32205 Equivalent Material has a robust microstructure that contains 40–50% ferrite. The corrosion resistance of the alloy's austenitic grades is still there despite this ferrite presence. This increases the stainless steel's resistance to pitting and crevice corrosion while also improving its performance in the majority of caustic situations.


Duplex Heat Resistance of UNS S32205 Duplex Stainless Steel Pipe


Despite having good high-temperature oxidation resistance, 2205 suffers from embrittlement if kept at temperatures above 300 oC for even a brief period of time, like other duplex stainless steels. If the steel is embrittled, only a thorough solution annealing treatment will be able to fix it. Nearly never are duplex stainless steels used over 300 oC. UNS S32205 Duplex Stainless Steel Pipe Duplex Heat Treatment: Solution treatment (annealing): heat to 1020°C–1100°C and quickly cool. This grade can work hard but cannot be thermally hardened.
