Material and Manufacturing Process
Each 316 SS Hex Reduced Shank Bolt DIN7964 is manufactured using AISI 316 stainless steel – a molybdenum-bearing grade that enhances corrosion resistance, particularly in chloride environments such as marine areas or chemical exposure zones. The manufacturing process involves cold forming or hot forging, CNC machining for reduced shank profiling, precision threading, deburring, and a surface treatment (passivation) for enhanced corrosion resistance.
Typical Applications and Industries
These bolts are commonly used in:
- Offshore and Marine Construction
- Chemical Processing Equipment
- Pressure Vessels and Piping
- HVAC Systems
- Pharmaceutical Manufacturing Environments
- Food & Beverage Equipment
- Infrastructure and Bridge Construction
Their high resistance to seawater and industrial chemicals ensures long service life and safety in critical environments.
