Metal materials are used in a myriad of applications in today's world. There are a wide variety of physical and chemical properties of metals that can be tailored to specific engineering applications. There are many reasons to conduct testing of metals both in the research stage when metal materials are being developed and in the application stage when they are being produced and used in specific applications. There are many types of tests that are available for metals. The following are some of the more common types of tests and the reasons for their importance: Chemical analysis: The composition of metal testing in Chennai is very important as it can dictate a number of properties once they are placed in service. These include corrosion resistance, creep resistance, strength, reaction to heat treatment, electrical properties, hardness/wear resistance, etc. Chemical analysis can be performed in a number of ways including Optical Emission Spectroscopy (OES), wet chemical analysis
