| High Light | Super Duplex S32750 Reducer ，Duplex Stainless Steel Reducer ，Butt Weld Pipe Reducer | ||
This super duplex S32750 S32760 stainless steel butt weld reducer is purpose-built for demanding corrosive environments where standard austenitic grades are not sufficient. Combining roughly equal amounts of austenite and ferrite, super duplex grades such as UNS S32750 and UNS S32760 deliver approximately twice the yield strength of 316L stainless steel together with outstanding resistance to pitting, crevice corrosion and chloride-induced stress corrosion cracking. The reducer is formed by seamless processing and finished with butt weld ends, making this super duplex stainless steel reducer the preferred solution for offshore platforms, seawater handling, desalination plants and chemical process piping operating under high chloride loads.
Because super duplex material is sensitive to heat treatment, our shop controls the forming temperature, cooling rate and solution annealing parameters precisely, then verifies the austenite-ferrite phase balance through metallographic testing and ferrite measurement. Impact testing and intergranular corrosion testing are performed on representative samples to confirm the mechanical properties of the super duplex stainless steel butt weld reducer. This careful thermal processing is essential to preserve the pitting resistance and toughness that make S32750 and S32760 grades perform reliably in seawater and sour service.

Q: What is the difference between S32750 and S32760?
A: S32750 (F53) and S32760 (F55) are both super duplex grades; S32760 adds tungsten and copper for further improved corrosion resistance in acid and seawater service.
Q: Can you provide NORSOK M-650 qualified material?
A: Yes, super duplex S32750 S32760 reducers can be supplied with NORSOK M-650 qualification and EN 10204 3.2 inspection for offshore use.
Q: What is the delivery time for super duplex reducers?
A: Typical delivery is 20 to 40 days depending on size, wall thickness and inspection requirements.
Q: Do you support custom dimensions?
A: Yes, custom diameters and schedules can be manufactured to your drawings.
Q: How do you verify the duplex phase balance?
A: We perform ferrite measurement and metallographic inspection on samples to confirm the correct austenite-ferrite ratio before delivery.
Please confirm the required material grade, end diameters, wall thickness schedule, applicable standard and quantity when placing your enquiry, and our team will respond with a detailed quotation, production lead time and available inspection options. Each fitting is cleaned and dried, then packed into reinforced plywood cases or pallets with clear shipping marks to prevent damage during transit. We support sea freight, air freight and express courier delivery, and provide packing lists, material certificates and other export documents before dispatch to keep your customs clearance smooth.
