Quality Control

Our Martensite reference materials are produced and characterized under controlled conditions to ensure microstructural consistency and purity. Each batch is validated through advanced metallographic techniques, including scanning electron microscopy (SEM) and X-ray diffraction (XRD), to confirm phase identity and absence of significant non-martensitic constituents. Certificates of Analysis (COA) detailing microstructure classification and recommended reference applications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). To prevent surface oxidation or contamination, store under an inert atmosphere such as argon or nitrogen for long-term preservation. Keep away from strong acids and corrosive environments.
