Material Introduction and Manufacturing Process
The A193 B8M stainless steel hexagon bolt is primarily made from 316 stainless steel, which contains molybdenum for enhanced corrosion resistance, especially in chloride-rich environments. This makes it particularly valuable in marine and chemical processing industries.
Manufacturing Process:
- Raw Material Inspection
- Cold Heading or Hot Forging to Hex-head Shape
- Thread Rolling or Thread Cutting
- Heat Treatment (if required for Class 2 bolts)
- Passivation or Electro-Polishing
- Dimensional and Mechanical Inspection
- Packaging
Each step of this process is monitored to ensure the bolt’s consistency, strength, and finish quality.
Applications in Various Industries
These bolts are engineered for demanding environments and find applications in sectors such as:
- Automotive and Heavy Vehicles
- Industrial & Commercial Construction
- Mechanical Equipment
- Power Generation and Energy Plants
- Household Appliances
- Marine and Offshore Platforms
- Aerospace and Railway Projects
- Electronics and Telecommunication Equipment
Because of their chemical resistance and tensile strength, A193 B8M bolts are especially valued in situations where ordinary fasteners would degrade.
