Is Duplex Fasteners Magnetic?
Duplex fasteners are designed with a dual-microstructure of austenitic and ferritic structure. The amount of ferrite in this grade leads to it being magnetic properties.
Is There Is Any Difference Between Duplex Screws Duplex Stainless Steel Bolts?
Many people consider a screw and bolt to be similar; however, they have different characteristics. A Duplex bolt is a non-tapered fasteners that uses a washer and nut to securely hold the object in place. A Duplex stainless steel screw has threads that allow it to mate with existing threads. It can create its own threads on the material it turns.
Features Of Duplex Bolts
The Duplex bolts are designed with a two-phase microstructure. These bolts show exceptional strength and can hold different equipment efficiently. A duplex bolt is designed with a superior chemical composition enabling it to showcase outstanding corrosion resistance properties. The bolts are very durable and can withstand pitting by acids in these harsh environments. Its outstanding mechanical properties allow it to have excellent heat resistance in the system. They also have high resistance to intergranular corrosion and work well in chloride and sulfide environments. The Duplex stainless bolts have higher tolerance to stress corrosion cracking. These bolts are well suited in lower temperature conditions and are easy to work with.
How Much Torque Does A Duplex Stainless Steel Stud Bolts Need?
Torque is generally used to create strong tension between threaded fasteners. The torque requirements vary based on the nominal diameters or if the device is lubricated or dry. Generally, a stud bolt has a yield strength of 70ksi, so calculation should be made accordingly. For a stud bolt with nominal diameters of 1/4 inches, the dry torque will be 6.5 ft-lb, with lubricated being 4.8 ft-lb. Similarly for nominal diameters of 1 inch, the dry torque will be 490 ft-lb, with the lubricated torque being 368 ft-lb.
