UNS S32760 is able to compete strongly with the 6% molybdenum “super austenitic” grades in some applications, as it has fewer amounts of Mo and Ni which drive up the base cost of the material. Although, 32760 has lower amounts when compared to “6% Moly” grades it still has higher contents of Cr, Ni, and Mo when referring to other alloys, these elements improve the intergranular and pitting corrosion resistance of the material.

The 904L stainless steel plate mainly uses a special corrosion-resistant alloy, mainly because the carbon content of this alloy is very low, which is several times lower than other models, so the probability of being corroded is greatly reduced. . We all know that in some areas with harsh environments, when stainless steel plates are used, the most worrying thing is that they will be corroded. Some of them will be corroded if they cannot last for a long time.

Super Austenitic 904L stainless steel tubes are designed for corrosive environments. By optimizing chemical composition, super austenitic 904L stainless steel tube is a super austenitic stainless steel with low C content and high alloying. 904L super austenitic stainless steel tube blank was successfully developed by specific production process.
characteristicAmong all stainless steels, super austenitic stainless steel has the most stringent technical requirements and is the most difficult steel. Because super austenitic stainless steel contains high content of nickel and molybdenum, as well as copper and nitrogen, it is not easy to melt, segregate and crack. Therefore, super austenitic stainless steel can become a technical caliber for steel mills.
OverviewThe concept of super austenitic stainless steel includes super ferritic stainless steel and super duplex stainless steel. A typical example is a super austenitic stainless steel containing 6% molybdenum and 7% molybdenum. These steel grades are specially developed for harsh industries such as petrochemical, chemical, paper and offshore systems.Development of Super Austenitic Stainless SteelTo deal with post-weld austenite intergranular corrosion susceptibility, titanium and tantalum were added early as carbide stabilizing elements.

Further, these elements present in Duplex steel gives versatile characteristics and abilities to finished product. It makes our products resistant to corrosion, cracking, pitting and crevice. Our company ensure to offer products with excellent chemical and mechanical properties. We make these seamless pipes with outstanding welding ability, oxidation and reduction procedures.
904L (N08904,14539) super austenitic stainless steel contains 24.0-26.0% nickel, 4.5% molybdenum. 904L super austenitic stainless steel is a low carbon, high nickel, molybdenum austenitic stainless steel, which is a special material introduced from H·S Company in France. It has good activation-passivation transformation ability and excellent corrosion resistance. It has good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid and phosphoric acid.
It is often said that the phase balance of duplex stainless steels is "50-50", which corresponds to the amount of austenite and ferrite. Strictly speaking, this is not true, as the ferrite content in modern duplex stainless steels is around 40% - 50% and the rest is austenite.
Duplex Stainless Steels are a specific group of engineering stainless steel materials consisting of the austenitic and ferritic phase in roughly equal proportions in the microstructure. They are widely popular because of their good corrosion resistance along with high strength and ease of fabrication. They are also popular by their acronym DSS.
