Analysis of the key points for selecting and using stainless steel bolts

2025 04/22

Key points for purchasing
Material selection: The main materials for stainless steel bolts are 304 and 316. 304 stainless steel has good corrosion resistance and high strength, suitable for general industrial and civilian fields; 316 stainless steel has better corrosion resistance, especially in highly corrosive environments such as the ocean or chemical industry.
Strength grade: The strength grade of stainless steel bolts is usually classified based on the tensile strength of the material, such as A2-70, A4-80, etc. A2-70 bolts have high strength and corrosion resistance, making them suitable for applications that require high-strength connections.
Surface treatment: The surface treatment method of stainless steel bolts will affect their corrosion resistance and aesthetics. Common surface treatments include polishing, galvanizing, blackening, etc. Galvanizing treatment can increase rust prevention ability, while blackening treatment can enhance aesthetics.
Application scenarios: Stainless steel bolts are widely used in fields such as construction, machinery, chemical engineering, and food processing. In the field of architecture, stainless steel bolts are used to fix doors, windows, glass curtain walls, etc; In the field of machinery, it is used to connect components such as transmission shafts and gearboxes; Used in chemical and food processing to resist corrosive media.
Key points for use
Environmental adaptability: Stainless steel bolts perform well in humid and corrosive environments, but attention should be paid to avoiding long-term immersion in water or strong acid and alkali environments to avoid affecting their corrosion resistance.
Installation precautions: During installation, ensure that the bolts and nuts are tightly fitted to avoid connection failure due to looseness. Use a suitable torque wrench for tightening to avoid over tightening and thread damage.
Maintenance: Regularly check the tightening status and surface condition of bolts, and replace damaged or loose bolts in a timely manner. In corrosive environments, it is recommended to regularly perform surface treatment to extend the service life.
