High strength cushion oxidized blackened cartridge washers are a type of washer designed for high-strength fastening applications where corrosion resistance and load distribution are critical. These washers are made from strong materials such as carbon steel or stainless steel and are treated with an oxidized blackening process to enhance their durability and resistance to corrosion.

Stainless Steel (304/316): Offers superior corrosion resistance and is suitable for moist or corrosive environments. The 316 grade has additional molybdenum, providing even better corrosion resistance, especially in marine applications.

Carbon Steel: Provides good strength and is the most common material for bolts. It may require additional surface treatments like galvanizing for increased corrosion resistance.

Alloy Steel: Offers enhanced strength and durability. It is often used in high-stress applications where high tensile strength is required.

Advantage:

High Strength: These washers are designed to handle significant pre-tensioning loads, making them suitable for use with high-strength bolts of grades 8.8 to 10.9 without any restrictions .

Corrosion Resistance: The oxidized blackening process provides a protective layer that resists corrosion, which is particularly important in environments exposed to moisture, chemicals, or extreme temperatures .

Load Distribution: The cushion design of these washers helps distribute the load from the fastener, reducing stress concentration and protecting the connected materials from damage.

Durable Finish: The blackened finish not only enhances the aesthetic appeal but also contributes to the wear resistance of the washer, prolonging the life of the fastener assembly .

Scope of Application

Automotive Industry: Used in the assembly of vehicles to secure components that require a reliable connection for safety and performance.

Aerospace: Employed in aircraft construction for high-strength connections that must withstand the rigors of flight.

Construction: Utilized in heavy machinery and structural support systems where strength and durability are essential.

Machinery: Used in various mechanical applications to ensure secure and stable fastening of components.
