Types of Stainless Steel Grades
In the field of industrial manufacturing and assembly, the choice of materials determines the performance and service life of products. As one of the most important materials in modern industry, stainless steel is widely used in fasteners and precision components due to its excellent corrosion resistance and mechanical strength. Many customers are concerned about the following when selecting products: What are the different grades of stainless steel? What are the specific applications for each grade of stainless steel?
As a professional manufacturer of industrial fasteners, Mocayo consistently selects high-quality stainless steel materials to produce its products, such as quick-release pins, indexing plungers, and spring plungers. Below, we will delve into this topic from the perspectives of stainless steel grade classification and product applications.

Types of Stainless Steel Grades
The most common types of stainless steel grades include the following categories:
Austenitic
Represented by 18-8 stainless steel, it has a high nickel content, excellent corrosion resistance, and good toughness, making it suitable for manufacturing components that require long-term stable operation.
