Duplex fasteners

Duplex stainless steel has high chromium and moderate nickel content in its alloy.The duplex fasteners have high tensile strength with increased hardness and toughness.The material is less likely to get deformed as well.The WNR 1.4462 dowel pin has mixed yet balanced austenite and ferritic structures, which contributes to its good mechanical properties.The alloy 2205 washer can show its optimal performance, even with low weight and leads to cost saving.

The UNS S31803 threaded rod shows good resistance to chloride ion related stress corrosion cracking.Duplex 2205 is one of the most widely used grades that show better corrosion resistance than the standard austenitic stainless steel.The ASTM A1082 UNS S32205 studs can also withstand pitting, crevice and stress corrosion cracking.However, they are difficult to machine and form.

India's first ever manufacturer of duplex 2205 fasteners as per ASTM A1082, know can duplex screws be used in harsh environments ?

The duplex screws have high strength and corrosion resistance, which makes them perfect for harsh environments.It can be used in highly acidic, alkaline, elevated temperature and chemical environments.

We are most reliable supplier of duplex bolts and nuts in Mumbai use for seawater equipment, check distinction between 316 and duplex 2205 bolts

• The duplex 2205 fasteners have higher chromium but lower nickel content than 316 ss.It also has dual ferritic and austenitic microstructure along with added nitrogen in the alloy unlike grade 316.
• Duplex 2205 has better corrosion resistance properties.
• 2205 grip fast duplex screws have higher mechanical strength & toughness and they can withstand higher loads than 316 stainless steel.
• The 2205 duplex screws are more expensive than the standard 316 ss grade.

• Super duplex is an upgraded version of duplex steel fasteners and hence they have higher chromium, nickel and molybdenum content.
• Super duplex offers better corrosion resistance due to the higher alloy content.
• The super duplex material offers higher mechanical strength than duplex stainless steel bolts.
• The duplex fasteners are more affordable than the super duplex ones.

• The duplex fasteners manufacturer recommends the following for proper bolt storage:
• They should be stored in a clean, dry and well-ventilated environment, away from contamination.
• They should be protected from weather elements including moisture from grounds.
• The duplex bolts must not come in direct contact with other materials, or galvanic erosion might occur.
• The packaging should be non-abrasive and they must not be stacked.
• The bolts should be regularly inspected to check for any signs of damage, contamination or corrosion.

• Determine the particular conditions of the application, including corrosion to determine if duplex steel fasteners are suitable for it.
• The applied load of the service should be compatible with the fasteners.
• Determine the temperature range of the application and see if it fits with the fasteners.
