Ultra-hard Core Precision Measuring Alloy Round Bar

Product Description

Ultra-hard Core Precision Measuring Alloy Round Bar

The tungsten steel piston rod, designed for ultra-high pressure, strong corrosion, and wide temperature change conditions, reconstructs the pressure measurement accuracy standard with 1900HV hardness + mirror-grade polishing (Ra≤0.05μm). In key areas such as deep well drilling, geothermal monitoring, and aviation hydraulics, it becomes the uncompromising rigid spine of the pressure gauge transmission system.
