Description
The 2205/2507/321 Stainless Steel Plain Washer is a heavy-duty washer designed to evenly distribute the load of a threaded fastener (bolt or screw) across a larger surface area, helping prevent damage to the material being fastened. Made from high-strength 2205 duplex stainless steel, 2507 super duplex stainless steel, or 321 stainless steel, these washers offer superior corrosion resistance, strength, and high-temperature resistance, making them ideal for demanding applications in harsh environments. Their exceptional durability ensures reliable performance in industries such as construction, automotive, marine, chemical, and food processing.
Features & Benefits
- High Corrosion Resistance: Manufactured from 2205, 2507, or 321 stainless steel, ensuring excellent performance in environments exposed to moisture, chemicals, or extreme conditions.
- Superior Strength & Toughness: Offers high tensile strength and impact toughness, with 2205 duplex stainless steel providing a yield strength of 400-550 MPa, twice that of austenitic stainless steels.
- Uniform Design & Precision: Features standard concentricity, smooth surface, and consistent circular shape for uniform load distribution.
- Large Load-Bearing Surface: The washer's large surface area ensures better load distribution, preventing material deformation, especially for softer materials.
