Magnetic Particle Testing (MT)
Magnetic particle testing (MT) is a nondestructive examination method used to detect surface and near-surface discontinuities in ferromagnetic materials. It is widely used for steel welds, forgings, shafts, and industrial components requiring reliable crack detection.

Manufacturing overview
Magnetic particle testing magnetizes a suitable ferromagnetic component and applies magnetic particles to reveal leakage fields associated with discontinuities.
The method may use visible or fluorescent particles under controlled inspection conditions.
Typical applications include welded steel structures, forged components, shafts, gears, and heavy machinery parts.
MT is suitable for ferromagnetic materials such as many carbon and alloy steels but is not generally applicable to nonferromagnetic materials such as aluminum or austenitic stainless steel.
Inspection effectiveness depends on magnetic field orientation, surface condition, material properties, and examination procedure.
Buyers should specify material grade, inspection zones, applicable standard, acceptance criteria, quantity, and reporting requirements.
Relevant standards may include ISO 9934 and ASTM E1444/E1444M.
Quality documentation may include examination records, indication evaluation, and equipment verification.
