3-Notch Eddy Current Standard, 4340 Steel, by PH Tool

This 3-Notch Eddy Current Standard by PH Tool is a precision-machined reference block made from 4340 Steel, specifically designed for calibrating, verifying, and setting up eddy current testing (ECT) equipment. It is an indispensable tool for ensuring the accuracy and reliability of flaw detection systems used to inspect ferromagnetic components, particularly those manufactured from 4340 steel or similar alloys.

Key Features & Benefits:

• Essential for ECT Calibration: Provides repeatable and known discontinuities for setting up eddy current instruments, verifying probe sensitivity, and establishing alarm thresholds for flaw detection.

• High-Quality 4340 Steel Material: Manufactured from AISI 4340 steel, a high-strength, low-alloy steel known for its toughness. Using a standard made from the same or similar material as the parts being inspected ensures relevant and accurate eddy current responses, accounting for material conductivity and magnetic permeability.

  
  

• Three Precision EDM Notches: The standard features three meticulously machined Electrical Discharge Machining (EDM) notches on the surface. These notches simulate fatigue cracks and other surface-breaking discontinuities, allowing for:

  
  

  • Calibration at different defect depths or sizes.

  • Verification of the system's ability to detect various flaw sizes.

  • Characterization of probe response to different crack-like indications.

• NIST Traceable Certification: All PH Tool standards are typically supplied with a certification report, providing traceability to the National Institute of Standards and Technology (NIST). This ensures the dimensional accuracy and material integrity, crucial for compliance with industry standards and audit requirements.

  
  

• Durable and Reliable: Crafted with PH Tool's renowned expertise in NDT standards manufacturing, ensuring long-term stability and consistent performance even with repeated use in industrial environments.

• Versatile Application: Primarily used in industries such as aerospace, automotive, power generation, and general manufacturing for the inspection of critical components where 4340 steel is utilized.
