An NL 3/4″ss double stack self-locking washer is a type of lock washer that is designed to prevent fasteners from loosening due to vibration or other forces. It consists of two stacked washers with angled teeth that bite into the mating surface and provide a locking action. The “NL” in the name stands for “nylon insert,” indicating that the washer has a nylon ring embedded in the top washer to provide additional locking force. The “3/4” refers to the diameter of the fastener it is designed to work with, and “ss” indicates that it is made of stainless steel. Overall, this type of washer is commonly used in various industries where secure fastening is essential, such as in aerospace, automotive, and manufacturing.

Material standard treatment of NL 3/4"ss double stack self locking washer

NL 3/4″ss double stack self-locking washer is a type of fastener that is commonly used in various industrial and mechanical applications. The material standard treatment for this type of washer typically involves the following steps:

Cleaning: The washer is thoroughly cleaned to remove any dirt, oil, or other contaminants that may be present on the surface. This can be done using solvents or other cleaning agents.

Passivation: The washer is then passivated to remove any iron particles or other impurities that may have accumulated on the surface during the manufacturing process. Passivation can be accomplished by immersing the washer in a nitric acid solution, which will dissolve any iron particles and leave the surface of the washer clean and smooth.

Annealing: The washer may then be annealed to improve its strength and durability.

Annealing involves heating the washer to a specific temperature and then allowing it to cool slowly. This process helps to remove any residual stresses that may be present in the material and can also improve the hardness and toughness of the washer.

Surface treatment: Depending on the application, the washer may undergo additional surface treatments such as coating or plating. Coatings can be applied to improve corrosion resistance, while plating can be used to provide additional strength or to enhance the appearance of the washer.

Overall, the standard treatment for NL 3/4″ss double stack self-locking washer typically involves a combination of cleaning, passivation, annealing, and surface treatment to ensure that the washer meets the necessary requirements for its intended application.
