PH Tool — 5-Step Calibration Block (Inconel 718, ASTM E797)
Precision UT Block for Thickness & Linearity Verification SKU: 5STEP.I718Overview
The PH Tool 5-Step Calibration Block is a precision ultrasonic reference standard designed for thickness measurement and linearity verification in ultrasonic testing (UT). Manufactured from Alloy 718 (Inconel), this block is ideal for calibrating equipment used on high-performance alloys commonly found in aerospace and high-temperature applications.
Featuring five precisely machined steps (0.100", 0.200", 0.300", 0.400", and 0.500"), the block allows inspectors to verify measurement accuracy across a range of thicknesses. Each step includes a 3/4" × 3/4" face, providing a stable and repeatable contact surface for consistent readings.
Built in accordance with ASTM E797 and supplied in inch configuration, this calibration block is delivered with a protective wooden case, making it suitable for laboratory, field calibration, and training environments.
