Mechanical testing is the methodology to test the material to verify the mechanical characteristics.  The mechanical test methods used determine the strength, and ductility of the material.  Each test performed is designed to give the mechanical characteristics and how the material will react to specific applications.  The mechanical testing is a certified way to verify that the material selected has been manufactured without flaws, heat treated to the specified requirements and holds to the mechanical properties that the material is designed to.

Chemical testing is the methodology to test the chemical make-up of the material.  The type of testing performed in the chemical testing would include determining the elemental composition of the material to verify that the correct concentrations were added during the manufacturing process of the material, to exposing the material to corrosive environments and evaluating how the material reacts to those specific environments.  All testing plays a key role in the manufacturing and end use of the product.  These tests assist in Engineering and determine specific applications the product is designed for and what services the material is suitable for.
