Industrial-Grade Carbon Steel Forging Services for Structural Fastening Systems
Product Overview :
We specialize in high-performance carbon steel forging for industrial fastening systems, delivering superior strength, reliability, and durability for demanding structural applications. Our precision forging capabilities produce heavy-duty studs, bolts, and connectors that meet the most rigorous industry standards.
Key Features & Benefits
✔ High-Strength Materials
Forged from ASTM A105, A350 LF2, 4140, and custom alloy steels
Enhanced grain structure for 30% greater fatigue resistance vs. machined or cast parts
Impact-tested for extreme load conditions
✔ Precision Forging Process
Closed-die forging for near-net-shape accuracy (±0.2mm tolerance)
CNC-machined threads and mating surfaces for perfect fitment
100% non-destructive testing (NDT) including ultrasonic and magnetic particle inspection
✔ Custom Engineering Support
DFM (Design for Manufacturing) optimization
Prototype-to-production services with fast turnaround
BIM/CAD compatibility for seamless integration
✔ Advanced Surface Treatments
Hot-dip galvanizing (85-120µm) for corrosion resistance
Xylan/PFPE coatings for chemical protection
Hardened surfaces for wear resistance
