Description
The 2205 Duplex Stainless Steel DIN 934 Nut is a top-tier fastener, designed to provide secure connections in environments where corrosion and stress are concerns. Designed to meet the DIN934 standard, this nut delivers superior strength, corrosion resistance, and dimensional accuracy, making it suitable for demanding fastening applications. Engineered to lock tightly, resist corrosion, and withstand heavy stress, this precision-engineered hexagon nut is the fastening solution of choice for marine, chemical, industrial, and structural applications where performance and safety cannot be compromised.
Features & Benefits
- Superior Strength: The 2205 duplex stainless steel has a yield strength of 400-550 mpa, which is twice that of common austenitic stainless steel. This hexagon nut also has good impact toughness.
- Corrosion Resistance: It offers excellent overall and local resistance to stress corrosion, making it a great choice for highly corrosive environments like chemical processing and marine structures.
- Secure Fastening: The nut is a standard hexagonal part that can lock tightly without slipping. Its deep threads ensure uniform force distribution.
