# Industrial Specification: Hydraulic Ram Assembly

## 1. Technical Definition
The hydraulic ram assembly is the primary force-generating component in a hydraulic press system, converting hydraulic pressure into linear mechanical force for bending metal.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **70-350 bar**. Failure boundary: **420 bar (yield strength of SAE 1045 steel at 250°C)**, Mechanism: **Cavitation-induced pitting at vapor pressure threshold of 0.023 bar absolute (at 20°C hydraulic oil), leading to surface fatigue and crack propagation**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.
