Material Overview and Manufacturing Process
A193 B8 stud bolts are manufactured from 304 stainless steel, an austenitic material known for its excellent corrosion resistance, malleability, and mechanical strength. For environments exposed to corrosive chemicals or high humidity, 304 stainless steel outperforms most alternatives due to its chromium and nickel composition.
Manufacturing Process:
- Raw Material Selection (Certified 304 steel rods)
- Cold Forming (Thread rolling or forging)
- Heat Treatment (Only for Class 2 – hardened for higher strength)
- Surface Treatment (Zinc-plating / Passivation)
- Inspection and Quality Control
- Packaging (Bulk, plastic boxes, pallet loads based on client needs)
Our production lines are fully automated and manned by a skilled technical team to ensure consistent quality across batches.
Application Fields
A193 B8 Stainless Steel Stud Bolts are widely used in heavy-duty and safety-critical applications. Typical use cases include:
- Automotive Manufacturing
- Construction Projects (Steel structures, bridges)
- Industrial Machinery
- Power Generation and Grid Equipment
- Electrical Appliances and Consumer Electronics
- Aerospace and Railway Engineering
- Telecom Towers and Marine Systems
These stud bolts are particularly suitable for high-pressure pipelines and systems exposed to extreme ambient or operational temperatures.
