What Are The Characteristics Of Stainless Screws?

Stainless screws are usually steel screws that have the ability to withstand the corrosive effects of air, water, acids, alkali salts or other media. Stainless steel screws are generally not prone to rust and corrosion. Can be used in environmental protection equipment, medical equipment, communication equipment and other fields.

Stainless steel focuses on rust and acid resistance depending on the composition of the alloy. Although some steels have rust properties, they are not necessarily acid-resistant, and acid-resistant steels usually have rust properties. In people’s daily life, stainless steel is often referred to as austenitic stainless steel. The stainless steel screws we use are mainly made of austenitic 302, 304, 316 and “low nickel” 201.

Stainless screws selection principle:

The choice of stainless steel materials is mainly considered from the following five aspects.

1. Requirements for mechanical properties, especially strength, of stainless steel screw materials;
2. Requirements for the corrosion resistance of the material under working conditions;
3. The requirements of the working temperature on the heat resistance (high temperature strength and oxidation resistance) of the material;
4. Requirements for material processing performance in terms of production process;
5. Other aspects. For example, weight, price, procurement and many other factors must be considered.
