Sachiya Steel International offers a wide range of Duplex Steel S31803 Threaded Forged Fittings, which are offered by us in variegated sizes and dimensions at industry leading rates. Duplex Steel S31803 Forged Threaded Elbow describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless. Duplex Steel S32205 Forged Threaded Tee is the most widely used duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades.
Duplex Steel S31803 Forged Threaded Cross is often used in Marine Industry and Shipbuilding: such as in Propellers and Shafts, Rudders, Shaft Seals, Pumps, Bolts and Fasteners, Valves, Instrumentation, Oil and Chemical Tankers. Meanwhile, these Duplex Steel S32205 Forged Threaded Cap are also being offered in different sizes and shapes to our customers. Even when the equipment has sufficient power, allowance must be made for higher spring – back caused by the high strength of Duplex Steel S31803 Forged Threaded Fittings.

In the solution annealed condition from about 1925 Degree F, Duplex Steel S32205 Forged Threaded Coupling has a microstructure with about 40 % – 50 % ferrite. Grain size of Duplex Steel S31803 Forged Threaded Union (expressed as a lamellar spacing) is fine, depending on product form. Duplex Steel S32205 Forged Threaded Bushing is difficult to form due to its high strength and work hardening rate.

Sachiya Steel International is one of the leading manufacturer and exporter of Super Duplex Steel S32750 Threaded Forged Fittings, where we customize these products on the basis of the requirements detailed by customers at industry leading rates.
Super Duplex S32750 Forged Threaded Elbow has 25 % chromium, 4 % molybdenum, and 7 % nickel.
The high – temperature strength of Super Duplex S32760 Forged Threaded Tee is basically the same as Type 430 in the range of 950 Degree C to 1150 Degree C. The high molybdenum, chromium and nitrogen content gives high resistance to chloride pitting and crevice corrosion attack and the duplex structure provides Super Duplex S32750 Forged Threaded Cross with exceptional resistance to chloride stress corrosion cracking.Super Duplex S32760 Forged Threaded Cap should be noted that the strength increases abruptly below 900 Degree C. Meanwhile, these Super Duplex S32750 Forged Threaded Fittings are also being offered in different sizes and shapes to our customers.
At high temperatures, above 2000 Degree F, Super Duplex S32760 Forged Threaded Coupling will become increasingly ferritic, becoming fully ferritic at temperatures just below the melting point.Super Duplex Steel S32750 Threaded Forged Fittings | Super Duplex Steel S32750 Threaded Forged Fittings | Super Duplex Steel S32750 Threaded Forged Fittings | Super Duplex Steel S32750 Threaded Forged Fittings | Super Duplex Steel S32750 Threaded Forged Fittings | Super Duplex Steel S32750 Threaded Forged Fittings | Super Duplex Steel S32750 Threaded Forged Fittings | Super Duplex Steel S32750 Threaded Forged Fittings | Super Duplex Steel S32750 Threaded Forged FittingsSuper Duplex S32750 Forged Threaded Union has higher nitrogen increases the temperature at which austenite is stable within the duplex structure.
