DIN 6796 Conical Spring Washers ISO 10690 Belleville Cupped Stainless Steel 316 A4 Purification

Description

DIN 6796 conical spring washers (ISO 10690), also known as Belleville washers, made from Stainless Steel 316 (A4), offer superior load-bearing capacity, excellent corrosion resistance, and outstanding vibration absorption. These washers are ideal for marine, offshore, chemical processing, food, pharmaceutical, and high-humidity environments, where durability and resistance to extreme conditions are essential. Ever Hardware provides custom made fasteners and customizable packaging.

Key Advantages

1. Enhanced Corrosion Resistance for Harsh Environments
• Superior to 304 stainless steel, 316 stainless steel contains molybdenum (Mo), which provides better resistance to chloride exposure, acids, and saltwater corrosion.
• Ideal for marine, offshore, desalination plants, chemical processing, and wastewater treatment facilities.

2. High Load Absorption & Secure Fastening
• Designed to handle high axial loads, these washers distribute force efficiently, preventing loosening and bolt fatigue.
• Maintains tension even in high-vibration and high-pressure environments.

3. Exceptional Vibration & Shock Resistance
• The cupped, conical design absorbs shocks and dynamic loads, reducing the risk of bolt loosening.
• Ideal for marine engines, power plants, automotive, and industrial machinery subject to strong mechanical forces.

4. Superior Fatigue & Wear Resistance
• The spring action maintains elasticity over repeated load cycles, ensuring long-term reliability.
• Reduces the risk of fastener failure due to stress and fatigue, making it an excellent choice for high-performance mechanical systems.

5. High Temperature & Chemical Resistance
• Resistant to acids, alkalis, and extreme temperatures, making it suitable for food processing, medical, and pharmaceutical industries.
• Maintains structural integrity in boilers, steam applications, and industrial heat exchangers.

6. Suitable for Hygienic & Sanitary Applications
• Non-reactive and easy to clean, making it compliant with food and medical-grade safety standards.
• Prevents contamination in hygienic environments like dairy, beverage, and pharmaceutical processing.

Common Applications
• Marine & Offshore Structures – Prevents corrosion in saltwater and high-moisture environments.
• Chemical & Petrochemical Plants – Resistant to acids, alkalis, and corrosive chemicals.
• Aerospace & Automotive – Provides secure fastening under vibration and load cycles.
• Power Plants & Heavy Machinery – Absorbs high mechanical loads and prevents fastener fatigue.
• Food, Beverage & Pharmaceutical – Maintains hygienic, corrosion-resistant fastening.

Conclusion

DIN 6796 Conical Spring Washers (ISO 10690) Stainless Steel 316 (A4) provide maximum corrosion resistance, high-load retention, and excellent durability, making them the ideal choice for marine, offshore, chemical processing, and hygienic applications where reliability in extreme conditions is crucial.
