Duplex stainless steel fasteners S32760 Zeron 100 threaded rod
1.Why stud is used instead of bolts?
Studs provide the ability to obtain much more accurate torque values because the studs don't twist during tightening as do bolts. Because the studs remain stationary during nut tightening, the studs stretch in one axis alone, providing much more even and accurate clamping forces
2. Zeron 100 thread rod material introduction
ZERON® 100 (F55 Duplex / 25Cr Duplex) is a super duplex stainless steel for use in aggressive environments.
Its properties include:
Resistant to pitting and crevice corrosion in warm seawater with a guaranteed corrosion performance (PREN > 40)
Lower more stable price compared to nickel based alloys
Excellent resistance to stress corrosion cracking in both chloride and sour environments
Superior resistance to sulfuric acid at most concentrations
Improved resistance over austenitic stainless to erosion corrosion and corrosion fatigue
High Strength (80,000 psi minimum Yield Strength) permitting designs to reduce weight versus other corrosion resistant alloys
Readily weldable using ZERON 100 filler metal

3. The thread rolling definiation
Thread rolling is a cold metal forging process that forms threads into the mirror image of a roller die. This
process is different from metal cutting, grinding, and chasing because it does not remove any metal to
create the desired profile. Instead, thread rolling uses hardened steel dies to displace and mold ductile
metals.
The tooth form of the hardened steel dies protrudes into the outside diameter of plain cylindrical blanks
to reform the surface. The extreme pressure from the dies causes the blank material to displace radially
outward into the crests of the thread pattern, thus producing a part with a thread mirroring that of the
die.
