METALLURGICAL LABORATORY TESTING SERVICES

Metallurgy is used to study and produce metals for many different industries. The information obtained by studying the physical and chemical behavior of metals can be used to determine the suitability of a metals for its end use. A tremendous amount of information can be gained by several methods of metallurgical testing. The microstructures of a metal can be evaluated to reveal traits like strength, toughness, ductility, and hardness along with a number of other important characteristics.

 

DNDT uses the information obtained by metallurgical testing and relates it to the day-to-day use of your materials. DNDT has the ability to perform a simple evaluation of the internal structure of a material and compare it to specific codes or standards. Our engineers will discuss the project requests and intended testing to generate a report with the information that will satisfy your testing needs.

 

DNDT has outfitted our metallurgical and supporting mechanical laboratory with some of the latest equipment to meet your testing needs with capabilities including:

  • Digital Microscopy
