Super Duplex 2507 Fasteners

Super Duplex 2507 fasteners are made of a stainless steel alloy containing 25% chromium, 4% molybdenum, and 7% nickel. Duplex 2507 is known for its high strength and excellent localized corrosion resistance to chloride. This alloy is widely used for its yield strength which is twice that of annealed austenitic stainless steels, like 304 and 316 stainless.

Super Duplex Corrosion Resistance

Chloride corrosion resistance is one of the key attributes of Super Duplex 2507 fasteners due to its specialty metal makeup. The high molybdenum, chromium and nitrogen content of Super Duplex provides these fasteners excellent resistance to chloride corrosion such as pitting and crevice attack, while its ferritic structure makes it very resistant to stress corrosion cracking in warm chloride environments. Super Duplex 2507 fasteners also provide uniform corrosion protection from organic acids such as formic and acetic acid, plus inorganic acids, especially those containing chlorides. In addition, 2507 fasteners are highly resistant to carbide-related intergranular corrosion due to their low carbon content (0.020% in weight).

Key Benefits

• Very high resistance to pitting, erosion and crevice corrosion, as well as corrosion fatigue
• Excellent resistance to stress corrosion cracking (SCC) in chloride environments
• High resistance to general corrosion in acids
• Very high mechanical strength
• Good weldability: Can be readily joined to itself or other materials
• High thermal conductivity
• Low coefficient of thermal expansion, close to that of carbon steel.

Super Duplex 2507 Uses

• Process and service water systems, ballast water systems, and desalinization plants utilize 2507’s resistance to chloride.
• Mechanical assemblies and infrastructure relies on Super Duplex 2507 fasteners and flanges for their ability to withstand a high mechanical load in seawater.
• Super Duplex 2507 fasteners are also used in offshore platforms, as well as oil & gas exploration and production to protect from seawater.
• Power industry flue-gas desulfurization systems and geothermal exploration units also rely on 2507 fasteners.

Huitong Group was established in 1978. After 38 years'development and innovation,by now,Huitong Group has set up multiple subsidiary companies.Among them,Zhengzhou Huitong Pipe Fitting Co.,Ltd.,with the indepent right of import and export, is mainly engaged in exporting steel pipe and pipe fittings for Huitong Group and assisting another subsidiary company of Huitong Group:Zhengzhou Huitong Machanical Equipment Co.,Ltd., in exporting machanical equipment.

Zhengzhou Huitong Pipeline Equipment Co.,Ltd.,with the strong support of Huitong Group,and years'development and innovation, are more and more professional in technical service and can manufacure products with all kinds of material,shape and size. Especially in elbows, tee, reducer, flange and pipe cap etc., we have gained more than 20 product patent, and hundreds of technology patent. Also,we have gradually taken an ireplacable role in High-pressure,high-temperature and anti-corrosion area. With the continuous construction of engery in China,such as petrol gas,electric power,etc.,our company has become the purchasing center of whole set fittings for such projects.In 2009,a foreign trade team established,is manily engaged in oil gas and electric power projects abroad.By now, our products have been exported to

Canada,Malaysia,Parkistan,UAE, Eygpt,the Middle East countries, etc.. We have passed the qualification of ISO9001:2000 and API quality certification system.
