Hardened 40Cr Alloy Steel Backbone Spines (60 HRC / 120 N.m Torsion)
Engineering Overview: Engineering guide on hardened 40Cr alloy steel backbone spines pinned through Euro profile cylinder waists to defeat heavy pipe wrench attacks.
Technical & Engineering Specifications
| Standard | TS007 3-Star / Sold Secure Diamond / EN 1303 Grade D |
|---|---|
| Reinforcement | Full-Length Vacuum-Hardened 40Cr Alloy Steel Spine |
| Spine Hardness | 58 - 62 HRC |
| Torsional Resistance | > 120 N.m Twisting Torque Load |
Central Waist Reinforcement
The 10 mm central waist around the M5 screw hole is vulnerable to bending attacks. High-security cylinders embed a hardened 40Cr alloy steel spine (60 HRC).
Structural Load Capacity
- Spine Anchorage: Pinned through both cylinder halves beneath the central cam.
- Torsional Strength: Withstands $>120\text{ N}\cdot\text{m}$ twisting torque without fracture, exceeding EN 1303 Grade D requirements.
