We, Piyush steel, are supplying, manufacturing and exporting the Super Duplex Steel UNS S32760 Round Bar to a variety of customers within and outside the country. We are known as a popular manufacturer of these round bars not only in our country but even outside the country across the globe. We thus have worldwide clients that trust in our round bars for different applications. Our duplex steel round bars are a choice of customers from industries like power, chemical processing, sugar and paper mills, construction, engineering, oil and gas, pharmaceutical and petrochemical industries. Our finished bars are used even in harsh conditions where other bars are not appropriate to use.
The reason is that we know which raw materials are best for making round bars that can cater to the needs of all types of industries. Our finished quality bars are appropriate even for aggressive environments where chlorides and halides are used. Such environments lead to corrosion, stress cracking, brittle and damage but Super Duplex Steel 1.4410 Round Bar are perfect for such conditions because of impressive properties they possess. We combine ferritic and austenitic grades of alloy to manufacture them. This features unique qualities into the bars making them suitable.

Info about alloy
The Super Duplex Steel UNS S32760 alloy comprises of elements like chromium, nickel, and molybdenum along with nitrogen, tungsten, and copper. This makes it highly alloy super steel. This alloy has high PREN that makes it useful in aggressive environments. Its ferritic austenitic microstructure is also responsible for such qualities. It has about 40 to 50 percent ferrite that makes it workable in the annealed condition. The ferritic grade use gives high strength whereas austenitic grades use to give it corrosion resistance properties. This makes it a common material for use in stress cracking that can occur due to the chlorine present in a practical solution.
Not only this, this alloy makes them perform well under the sour-gas environments where other bars undergo sulfide stress corrosion cracking but our round bars have resistance against even to such environments. This is due to the use of UNS S32760 alloy. It is also known for high impact strength that leads to the brittle condition. However, the impact of energy gets reduced due to decrease in temperature. In welding condition, it also shows a reduction in impact strength but this is also slightly so makes not much difference.
This alloy was earlier used as a material that provides resistance against seawater corrosion. This makes it a great choice in pump applications and now it is also used in oil and gas application, heat exchangers, subsea pipe work systems and seawater.
Round bars come in different specifications where their shapes, sizes, and dimensions differ. They may vary in these specifications but possess the same properties. The customers can thus choose from wide category depending upon the place where they are using. Their properties are highly deciding factor to know which type works best for a particular application. The properties are significant but the right manufacturing process can yield better properties. We use only the right methods, tools and machinery to get the most out of the raw material. Proper and on time inspection of raw materials that lead to better quality product production. Our unit has experts for inspection in every department of the production line. At the final stage, it again undergoes inspection where it is checked by outside professionals. They give our products certificates of quality. This has great importance for our customers thus we share these certificates and test reports with them. They can ask for them anytime.
After complete production, packaging step is our next crucial steps. We use only environmentally friendly materials to pack them whilst ensuring their safety from the outside atmosphere.
The UNS S32760 Super Duplex Steel Bars have a chemical composition of 24.0-26.0% chromium, 6.0-8.0% nickel, 3.0-4.5% molybdenum, 1.2% manganese, 0.14-0.20% phosphorus, and 0.035% sulfur as well as a content of nitrogen of 0.18-0.25%. The alloy also consists of other trace elements, including iron and carbon, responsible for its high mechanical strength, excellent corrosion resistance and improved weldability compared to austenitic stainless steels such as 316L or 317L grades.
Super Duplex UNS S32760 round bars are highly alloyed stainless steel and offer outstanding features. They have excellent corrosion resistance, especially in chloride-bearing environments, high mechanical strength, and outstanding welding characteristics. The welding characteristics include good toughness even at cryogenic temperatures, high fatigue strength, beneficial microstructure stability with low sensitivity to hot cracking, and excellent formability for forging applications. Super Duplex UNS S32760 round bars also deliver exceptional pitting resistance, enabling them to be used in some of the harshest environmental conditions possible.
