Alloy 20 Spring Washer:

Function: Spring washers, also known as lock washers, are designed to provide a preload on a fastener and prevent loosening due to vibrations or dynamic loads. They create tension to prevent nuts and bolts from coming undone.

Material: Alloy 20, ensuring corrosion resistance and durability in challenging environments.

Applications: Similar to flat washers, spring washers made from Alloy 20 are used in environments where corrosion resistance is essential, such as in chemical and petrochemical industries.

When using fasteners and washers in corrosive environments, it's crucial to select materials that can withstand the specific conditions of the application. Alloy 20 is often chosen for its resistance to sulfuric acid and other corrosive substances. Additionally, it's advisable to follow industry standards and guidelines for installation and maintenance to ensure the longevity and effectiveness of the components.
