NM01GRAY1

Gray Magnetic Inspection Powder #61 is a finely milled, nonfluorescent magnetic particle powder specifically designed for the dry method of Magnetic Particle Inspection (MPI). This essential consumable in non-destructive testing is used to effectively reveal surface and shallow subsurface discontinuities in ferromagnetic materials such as iron, steel, nickel, cobalt, and their alloys.  

When applied as a dry powder to a magnetized surface, these fine gray particles are readily attracted to areas of magnetic flux leakage created by defects like cracks, seams, laps, and inclusions. The accumulation of the gray powder along these leakage paths forms a visible indication of the flaw under standard lighting conditions, allowing for straightforward identification.  

Key Selling Points:

• Optimized for Dry MPI Applications: Specifically formulated for effective use in dry magnetic particle inspection techniques.  

• Excellent Contrast Under Visible Light: The nonfluorescent gray color provides clear and easily visible indications on various material surfaces.  

• Effectively Reveals Surface and Near-Surface Flaws: Reliably highlights cracks, seams, laps, and inclusions in ferromagnetic materials.  

• Versatile for a Range of Ferromagnetic Materials: Suitable for inspecting components made from iron, steel, nickel, cobalt, and their alloys.

• Simple and Economical Application: Applied easily by dusting or blowing onto the magnetized part, offering a cost-effective inspection solution.

• Suitable for Higher Temperature Applications: Can be used in situations where wet methods are impractical due to elevated temperatures (temperature limits vary by manufacturer).  

• Meets Industry Quality Standards: Manufactured to comply with relevant industry specifications such as ASTM E1444 and other applicable standards.  

Benefits:

• Provides Clear and Easily Interpreted Indications: The gray powder builds up well at defect locations, making identification straightforward.  

• Enhances Detection Reliability: Enables the identification of surface and near-surface flaws that may be invisible to the naked eye.  

• Offers Versatility in Application: Suitable for inspecting various component geometries and surface conditions where dry MPI is preferred.

• Cost-Effective Quality Assurance: Provides an economical method for ensuring the integrity of ferromagnetic materials.  

• Simple Integration into Existing MPI Procedures: Requires minimal training and integrates easily into standard inspection workflows.

Applications:

Gray Magnetic Inspection Powder #61 is widely used for the inspection of a diverse range of ferromagnetic components and weldments across various industries, including:

• Inspection of structural steel components and welds.

• Examination of castings and forgings for surface defects.  

• Quality control of automotive parts and assemblies.

• Non-destructive testing of pipes and pressure vessels.  

• Inspection of machinery and heavy equipment.

• General MPI applications on ferromagnetic materials.

Gray Magnetic Inspection Powder #61 is a dependable and economical consumable for dry magnetic particle inspection, providing clear, visible indications of surface and near-surface defects in ferromagnetic materials under normal lighting, contributing to effective quality control and safety.
