Anti-Snap Center Bridge Reinforcements: 40Cr Alloy Steel Tension Bars
Engineering Overview: Technical breakdown of hardened 40Cr alloy steel connecting bridges reinforcing Euro profile cylinder waists against bending and snapping attacks.

Eliminating the Euro Profile Weak Point
The standard Euro teardrop profile narrows to a 10 mm waist at the M5 screw hole. Applying 50 N·m torque can snap standard brass bodies in half.
40Cr Hardened Steel Spine Architecture
High-security cylinders embed a hardened 40Cr alloy steel reinforcing bar (58–62 HRC) through the center bridge:
- Bending Resistance: Increases torsional yield strength to $>120\text{ N}\cdot\text{m}$.
- Tensile Anchorage: Holds both cylinder halves together even if the outer brass body is heavily attacked.
Frequently Asked Engineering & Selection Questions
Q1: What material is used for high-security anti-snap bridges?
Hardened 40Cr alloy steel bars (58-62 HRC) are pinned through the central waist to bridge both cylinder halves against high-torque bending.
