Product Description
Introduction：Stainless steel Super Duplex 2507 is designed to handle highly corrosive conditions and situations were high strength is required. High molybdenum, chromium and nitrogen content in Super Duplex 2507 help the material withstand pitting and crevice corrosion. The material is also resistant to chloride stress corrosion cracking, to erosion corrosion, to corrosion fatigue, to general corrosion in acids. This alloy has good weldability and very high mechanical strength. SuperDuplex stainless like Duplex, is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades. The main difference is that Superduplex has a higher Molybdenum and Chromium content which gives the material greater corrosion resistance. SuperDuplex has the same benefits as its counterpart – it has lower production costs when compared with similar ferritic and austenitic grades and due to the materials increased tensile and yield strength, in many cases this gives the purchaser the welcomed option of purchasing smaller thicknesses without the need to compromise on quality and performance.Benefits of UNS32750 SuperDuplex Stainless Steel* Improved corrosion resistance in comparison to Duplex* Greater tensile and yield strength* Good ductility and toughness* Good stress corrosion cracking resistance (SSC)* Opportunity for purchases to reduce their material costs without compromising on quality

Socket Welding Flanges introduction：
Socket welding Flanges are flanges where the pipe end is inserted into the flange ring step and welded to the pipe end and outside. They come in two types: with neck and without neck. Necked flanges have better rigidity, less welding deformation, and better sealing performance, and can be used in applications with pressures of 1.0~10.0 MPa. Type B flanges for vessels are also socket welding flanges, used in applications requiring high sealing performance. During design, socket welding flanges can be checked as integral flanges.
