In the material selection of stainless steel spring washers, 304 and 316 stainless steel are the two most commonly used materials. The following is a detailed introduction to these two materials of stainless steel spring washers:

1. 304 stainless steel spring washer

• Features: 304 stainless steel is one of the most widely used austenitic stainless steels, with good corrosion resistance, mechanical properties, and excellent processing performance. It contains 18% -20% chromium (Cr) and 8% -10% nickel (Ni), which allows it to maintain stable performance in many corrosive environments.
  

• Application: 304 stainless steel spring washer is suitable for general corrosive environments and widely used in fields such as mechanical manufacturing, automotive manufacturing, electronic devices, etc.

2. 316 stainless steel spring washer

• Features: 316 stainless steel adds molybdenum (Mo) element on the basis of 304 stainless steel, and the nickel (Ni) content is increased by 2% -3%. This makes 316 stainless steel more resistant to chloride ion corrosion and suitable for marine environments or chemical environments containing chloride ions. At the same time, 316 stainless steel has higher creep resistance when the temperature rises.
  

• Application: 316 stainless steel spring washers have a wide range of applications in fields such as marine engineering, chemical equipment, and food processing equipment.

3. Choose Suggestions

When choosing the material of stainless steel spring washers, comprehensive consideration should be given to the specific usage environment and requirements. For example, in marine environments, due to the presence of a large amount of chloride ions, stainless steel materials such as 316 that are resistant to chloride ion corrosion should be selected. In general corrosive environments, 304 stainless steel spring washers are a cost-effective choice.

In summary, 304 and 316 stainless steel are the two most commonly used materials in stainless steel spring washers, each with unique characteristics and applicable ranges, which can meet the needs of different fields of use.
