FAQ's of DUPLEX 2205 HEX BOLTS M20X100:

Q: How are DUPLEX 2205 HEX BOLTS M20X100 typically used in industry?

A: These bolts are used for fastening in structural projects, marine constructions, and chemical processing plants, where both mechanical strength and resistance to harsh environments are critical.

Q: What benefits do DUPLEX 2205 HEX BOLTS offer over standard stainless steel bolts?

A: They deliver significantly enhanced strength and superior corrosion resistance, especially in chloride-rich settings, leading to greater longevity and safety compared to conventional stainless fasteners.

Q: What is the process for manufacturing DUPLEX 2205 HEX BOLTS M20X100?

A: These bolts are manufactured from Duplex Stainless Steel 2205, solution annealed for optimal microstructure, and finished with shot-blasting or polishing, ensuring consistent quality and performance.

Q: When should DUPLEX 2205 HEX BOLTS be selected over other grades?

A: They should be selected for projects where both high strength and exceptional resistance to pitting or crevice corrosion are required, especially in environments exposed to chlorides or corrosive chemicals.

Q: Where can DUPLEX 2205 HEX BOLTS safely operate regarding temperature?

A: They function reliably within an operating temperature range from -50C to 300C, covering many industrial and marine applications.

Q: How do the magnetic properties of DUPLEX 2205 HEX BOLTS affect their use?

A: These bolts are slightly magnetic due to the ferrite phase in their microstructure, which does not significantly impact most applications but should be considered where non-magnetic fasteners are required.
