What is a steel washer?

A commonly used mechanical part, mainly used to protect the surface of the connected parts from being scratched by the nut, and to disperse the pressure of the nut on the connected parts. They are usually flat metal rings, and the material can be metal, such as stainless steel, carbon steel, etc. These materials have good mechanical properties and corrosion resistance, and can adapt to various working environments.

Stainless steel washers: The most common ones are 304 stainless steel and 316 stainless steel. These two stainless steels have good corrosion resistance and high temperature resistance and are suitable for a variety of working environments. 304 stainless steel washers are suitable for working environments with temperatures not exceeding 760°C, while 316 stainless steel washers are suitable for working environments with temperatures not exceeding 815°C. These two stainless steel washers are widely used in situations that require high strength and corrosion resistance due to their excellent corrosion resistance and high temperature resistance.

Carbon steel washers: Carbon steel washers have good plasticity and toughness, as well as good weldability. The strength and hardness of carbon steel washers increase with the increase of carbon content, but the plasticity, toughness and weldability will decrease accordingly. Carbon steel washers are widely used in general industrial and civil fields due to their good mechanical properties and cost-effectiveness.

The design and selection of steel washers are based on the specific working environment and application requirements to ensure that they can effectively protect the connected parts while maintaining good mechanical properties and durability. Different types of steel washers have their own characteristics and are suitable for different working conditions and requirements, thus ensuring the stability and reliability of the connection.
