Metals and Alloys

Metallurgy is the study of physical and chemical behavior of metals and alloys. Study of microstructure and its correlation with the properties of materials and their behaviour in the service condition is an important aspect of metallurgy.

At Criterion Scientific, we donít just provide instrument generated data or results but rather provide comprehensive results and reports solving your core problem at affordable cost. In doing so, our engineers and scientists practice a highly collaborative style with our clients.

Our teams from various labs work closely with each other. They combine their mechanical, chemical, metallurgical, biological and biomedical expertise to solve your materials problems and deliver rapid, accurate and cost effective solutions to you.

We perform tests in accordance with various national and international standards including the the American Society of Mechanical Engineers (ASME), American Society for Testing and Materials (ASTM), British Standards (BS) and German Standards (DIN). We also perform custom tailored materials and product testing services to suit and correlate your materials/productís service and application conditions.
