Description
The 2205 Duplex Stainless Steel DIN9021 Large Thick Flat Washer is a premium-grade washer engineered for high-performance fastening in extreme environments. Designed according to DIN 9021 standards, this Thick Flat Washer features a large outer diameter and increased thickness, ensuring enhanced load distribution, surface protection, and structural stability. Made from 2205 duplex stainless steel, this flat washer offers exceptional mechanical strength, superior corrosion resistance, and outstanding stress corrosion cracking resistance - ideal for heavy-duty and corrosive applications such as marine, offshore, and chemical processing industries.
Features & Benefits
- Exceptional Strength: With a yield strength of 400–550 MPa, 2205 duplex stainless steel provides twice the strength of common austenitic stainless steels.
- Superior Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, ensuring durability in marine and chemical environments.
- High Dimensional Precision: Manufactured to DIN9021 standards with smooth surfaces, precise concentricity, and uniform thickness for stable load transfer.
- Enhanced Load Bearing: Large outer diameter and thick design distribute fastening loads evenly, reducing surface damage and increasing joint stability.
