Our team of qualified and experienced metallurgists provides a wide range of testing activities.

Metallography is the study of materials' microstructure. Analysis of a material's microstructure helps to establish if the material has been processed correctly and is a critical step in determining product reliability and for understanding why a material failed.

The basic steps for correct metallographic specimen preparation include grinding and polishing, and etching to reveal the structure of the specimen.

Metallographic and materialographic specimen preparation seeks to find the true structure of the material. 

Corrosion Testing -  Intergranular, pitting and rate corrosion testing services, covering austenitic stainless steels and wrought nickel rich chromium bearing alloys is also carried out by our Metallurgy Department.
