Description
The 2205 SS Hex Nut is a high-performance fastening component manufactured from duplex stainless steel 2205 and designed in accordance with the GB6170 standard. This thick hexagonal nut is engineered for demanding applications that require exceptional mechanical strength, superior corrosion resistance, and long-term fastening reliability.
As a duplex stainless steel fastener, the 2205 SS Hex Nut combines the advantageous properties of both austenitic and ferritic stainless steels. This results in a fastening solution with significantly higher yield strength, excellent resistance to stress corrosion cracking, and outstanding durability in harsh environments. It is widely used across marine, chemical processing, construction, and heavy-duty industrial sectors.
Features & Benefits
- Superior Strength: The 2205 SS Hex Nut has a yield strength of 400-550 mpa, which is twice that of common austenitic stainless steel. It also features good impact toughness.
- Corrosion Resistance: It offers excellent overall and local resistance to stress corrosion. This makes it a great choice for marine and chemical environments.
- Secure Fastening: The nut is a standard hexagonal part that locks without slipping. Its deep threads ensure uniform force distribution, making it easy to lock tightly.
- Reliable Fastening: Engineered to “lock tightly,” reducing the risk of loosening during operation.

FAQ:
Q1: What makes 2205 Duplex superior to 316 stainless steel?
A: The 2205 grade offers nearly double the yield strength of 316 stainless steel and significantly higher resistance to stress corrosion cracking, particularly in high-chloride environments.
Q2: Does this 2205 SS Hex Nut meet international standards?
A: Yes, these nuts are manufactured to comply with the GB6170 standard, ensuring consistent dimensions and mechanical performance for global industrial use.
Q3: Why is the "thick" design important for these hexagonal nuts?
A: The thick hexagonal profile provides more thread engagement, which allows for higher torque application and a more secure, reliable lock that resists stripping under extreme pressure.
Q4: Can these nuts be used in underwater applications?
A: Absolutely. The 2205 Duplex material is specifically designed for marine environments where standard stainless steel might succumb to pitting or crevice corrosion.
Q5: Can this nut be used in structural applications?
A: Yes. Its high strength and reliable locking performance make it suitable for structural and heavy-duty industrial fastening applications.
