Metallurgical Analysis

Metallurgy is the process and technology that extract metals or metal compounds from minerals and make these metals into metal materials with certain properties by a variety of processing methods. Metallurgical analysis reveals the condition and composition of the material through macro, micro and SEM inspection. These analyses reveal the microstructure of the material, the processes performed during the manufacturing process, and whether the material characteristics meet the required specifications to ensure durability and safety for the intended use.

STEMart carries out microscopic and macroscopic examinations to identify defects, determine microstructure, evaluate treatments and ensure conformance to specifications.
