Hardness testing to ISO 6508-1
The DIN 7989 washer is a specific type of washer made from stainless steel, a material known for its exceptional corrosion resistance and durability. These washers are designed to be used in various applications where a secure and long-lasting fastening solution is required.
Key characteristics of the stainless steel DIN 7989 washer include:
1. Material: These washers are constructed from stainless steel, a versatile alloy that is composed primarily of iron, chromium, and nickel. Stainless steel is highly resistant to rust, staining, and corrosion, making it ideal for outdoor and marine applications.
2. Shape: DIN 7989 washers are generally flat, circular discs with a hole in the center. The large outer diameter of these washers provides a broad surface area for distributing loads evenly.
3. Function: They are commonly used in conjunction with bolts or screws to provide additional support and distribute the load over a broader surface area. This helps prevent deformation or damage to the connected materials.
4. Size: DIN 7989 washers come in various sizes and thicknesses to accommodate different fastener dimensions and applications. Their size should be chosen according to the specific requirements of the project.
5. Applications: These washers find application in a wide range of industries, including construction, automotive, machinery, and general manufacturing. They are especially useful in heavy-duty and structural applications where stability and load distribution are critical.
6. Advantages: The stainless steel construction offers several advantages, such as resistance to corrosion, ease of maintenance, and a polished appearance. This makes them a preferred choice for outdoor and exposed environments.
7. Compliance: DIN 7989 is a standard specification defined by the Deutsches Institut für Normung (DIN), which is the German Institute for Standardization. Compliance with this standard ensures that the washers meet specific requirements for dimensions and performance.
