DIN 127 Spring Washer ISO 7090 Washer Stainless Steel 316 A4 Purification

Description

DIN 127 Spring washer (ISO 7090) made from Stainless Steel 316 (A4) provide superior corrosion resistance, high durability, and reliable fastening security in extreme and harsh environments. These washers are ideal for marine, chemical, pharmaceutical, and purification applications, where exposure to saltwater, acids, and chemicals is common. Their spring tension mechanism prevents loosening caused by vibrations, thermal expansion, or mechanical stress, ensuring secure and long-lasting connections. Ever Hardware provides custom made fasteners and customizable packaging.

Key Advantages

1. Excellent Anti-Loosening Properties
• Spring-like tension applies continuous pressure on the fastener, preventing it from loosening due to vibrations, shocks, or temperature fluctuations.
• Provides secure fastening in dynamic and high-stress environments.

2. Superior Corrosion & Chemical Resistance
• 316 stainless steel (A4) contains molybdenum, making it highly resistant to chlorides, acids, and harsh chemicals.
• Performs exceptionally well in marine, offshore, and industrial environments where 304 stainless steel may corrode over time.

3. High Strength & Durability
• Stronger than 304 stainless steel, offering greater resistance to wear, deformation, and fatigue.
• Maintains elasticity and shape even after prolonged use in high-pressure and high-vibration conditions.

4. Suitable for Hygienic & Purification Applications
• Non-porous, smooth surface prevents bacterial growth, making it FDA-compliant for food processing, pharmaceutical, and water treatment applications.
• Easy to clean and resistant to contamination.

5. Resistance to Extreme Temperatures & Environmental Factors
• Can withstand temperatures up to 870°C (1600°F), making it suitable for high-temperature industrial applications.
• Highly resistant to UV rays, humidity, and environmental pollutants, ensuring long-term outdoor performance.

6. Versatile for Multiple Applications
• Widely used in marine, chemical processing, purification, food, pharmaceutical, aerospace, and structural applications.
• Compatible with various fastening systems, including structural, mechanical, and precision engineering.

Common Applications
• Marine & Offshore Structures – Ideal for saltwater exposure and harsh weather conditions.
• Chemical & Purification Plants – Resistant to corrosive acids, chemicals, and moisture.
• Food & Pharmaceutical Equipment – Hygienic and contamination-free fastening.
• Aerospace & Automotive – Ensures vibration resistance and secure connections.
• Structural & Industrial Machinery – Maintains fastener integrity in high-stress environments.

Conclusion

DIN 127 spring washer (ISO 7090) Stainless Steel 316 (A4) offers unmatched corrosion resistance, superior fastening security, and excellent durability, making them the preferred choice for marine, chemical, food processing, pharmaceutical, and purification applications.
