High-Strength 440B Stainless Steel Arc Connectors | CNC Machined Corrosion-Resistant Couplers

CNC machined high-strength 440B stainless steel arc connectors. Excellent corrosion resistance for demanding applications.

Core Parameters

Design Advantages

• Bio-inspired Arc Optimization:

  • Available in R5-R50mm curvature radii

  • Stress-dispersing grooves reduce peak stress by 30%

• Self-lubrication Options:

  • Laser-microtextured oil reservoirs (0.1mm depth)

  • FDA-compliant embedded PTFE bushings

• Quick-connect Mechanism:

  • Eccentric cam locking system

  • Single-hand operation (<8N·m torque)

Process Control

• Heat Treatment Integration:

  • Rough machining → vacuum hardening → finish machining (0.1mm allowance)

  • Cryogenic treatment (-80°C×4h for dimensional stability)

• Curved Surface Machining:

  • 5-axis flank milling (eliminates ball-end tool marks)

  • In-process laser profilometry

• Rust Prevention:

  • Post-machining passivation (nitrate/dichromate)

  • VCI packaging (2-year rust-free storage)

Quality Certification

• Rockwell hardness gradient map

• CMM arc profile scan data

• Metallographic analysis (≥95% martensite content)
