Duplex Steel Fasteners

Steel Tubes India are the leading manufacturer of high integrity Duplex Steel Fasteners (e.g. bolts, set screws, stud-bolts, nuts and washers), meeting clients’ exacting demands for critical applications in hostile environments. Whether for offshore (buoyancy and petrochemical), seawater, pump, valve or nuclear, the demands for an exceptional service and supply is never ending. We believe manufacturing bolting in exotic materials is an art form and it is something we have perfected at Steel Tubes India

Our Duplex Steel Fasteners product range includes Duplex Steel Bolts, Hexagon head bolt, Hexagon head screw, Round head square neck bolt, Hexagon socket head cap screw in full thread and half thread, Hexagon wood screw, Hexagon socket button head screw, Hexagon socket button flange screw, Hexagon socket counter sunk head cap screw in full thread and half thread, square nuts, square weld nuts, hexagon weld nuts, thick nyloc nuts, hexagon flange nuts, threaded rods, dowel screws, Plain / Flat Washer, Spring Washers, Countersunk Washer,Tooth Lock Washer and many more. We provide products as per DIN, ANSI, JIS standards.

Steel Tubes India  produces duplex fasteners in all grades of duplex, to customer specification. Duplex grades are a mixed microstructure of Austenite and Ferrite, combining the properties of both (hence the name DUPLEX). Duplex stainless steels have high corrosion resistance as well as a high strength. Mechanical properties are around double that of a typical austenitic grade such as 316. They would also normally offer higher stress cracking resistance in Chloride solutions for example. If we do not have your Duplex Steel Fasteners in stock (Inch or Metric) we can have these manufactured to your specification.

  • Duplex stainless steels have a two-phase microstructure of austenite and ferrite grains.The duplex structure gives this family of stainless steels a combination of attractive properties:Strength:

  • Duplex stainless steel is about twice as strong as regular austenitic or ferritic stainless steels.Toughness and ductility:

  • Duplex stainless steel has significantly better toughness and ductility than ferritic grades; however, they do not reach the excellent values of austenitic grades.

  • Corrosion resistance: As with all stainless steels, corrosion resistance depends mostly on the composition of the stainless steel. For chloride pitting and crevice corrosion resistance, their chromium, molybdenum and nitrogen content are most important. Duplex stainless steel grades have a range of corrosion resistance, similar to the range for austenitic stainless steels, i.e from Type 304 or 316 (e.g. LDX 2101©) to 6% molybdenum (e.g. SAF 2507©) stainless steels.

  • Stress corrosion cracking resistance: Duplex stainless steel shows very good stress corrosion cracking (SCC) resistance, a property they have "inherited" from the ferritic side. SCC can be a problem under certain circumstances (chlorides, humidity, elevated temperature) for standard austenitics such as Types 304 and 316.

  • Cost: Duplex stainless steel has lower nickel and molybdenum contents than their austenitic counterparts of similar corrosion resistance. Due to the lower alloying content, duplex stainless steel can be lower in cost, especially in times of high alloy surcharges. Additionally, it may often be possible to reduce the section thickness of duplex stainless steel, due to its increased yield strength compared to austenitic stainless steel. The combination can lead to significant cost and weight savings compared to a solution in austenitic stainless steels.
