Austenitic stainless steel, aluminium and nickel alloys cannot be magnetised, so magnetic particle inspection is not an option. The cracking mechanisms do not care: thermal fatigue, chloride stress corrosion cracking and weld solidification cracks still open to the surface, and still propagate to failure.
Liquid penetrant testing works by capillary action instead of magnetism. A coloured or fluorescent penetrant is drawn into any surface-breaking discontinuity, the excess is removed, and a developer draws the trapped penetrant back out into a high-contrast indication many times wider than the crack itself. The technique is governed by ASME Section V Article 6 and ISO 3452-1.
Glospech PT teams inspect stainless and non-ferrous welds, machined components and castings across Gauteng and Mpumalanga, with on-the-spot evaluation and a written report within 24 hours.

Visible Colour-Contrast Dye Penetrant
Red dye penetrant with white developer: high-contrast indications in daylight
Works on any non-porous material: stainless steel, aluminium, carbon steel, nickel alloys
Ideal for site welds, flange faces and repair verification
Code: ASME Section V Article 6 / ISO 3452-1
What PT detects
Surface-breaking cracks · Solidification and crater cracks · Surface porosity · Surface lack of fusion · Laps and cold shuts
Fluorescent Penetrant (UV-A)
Fluorescent penetrant under UV-A light for maximum sensitivity
Fine, tight discontinuities on machined and critical components
Workshop or enclosed, darkened site conditions
Solvent-removable or water-washable systems selected to suit the component
Applicable codes
