Chemical Testing

Inorganic Elemental Analysis ensures the quality of our raw materials and monitors control of processes our materials are subjected to. Chemical testing is generally performed to inspect for conformance to customer specifications and material industry standards. Content of oxygen, nitrogen, and hydrogen are determined simultaneously by an inert gas fusion technique as well as thermal conductivity and infrared detections. Carbon and sulfur are determined simultaneously using a combustion technique and infrared detection. Hydrogen content is particularly critical to our titanium alloys and other refractory metals. Hydrogen has a tendency to penetrate grain boundaries and cause delayed embrittlement. For this reason, FWM certifies the hydrogen content of all titanium alloys upon final inspection. Reference test method standards are ASTM E1447, ASTM E1409, ASTM E1019, and ASTM E1941 depending on the base alloy and the test technique.

Electrochemical Corrosion Testing allows us to observe the breakdown of our products in order to predict the weakening or destruction of metals over an extended period of time in a simulated biological environment. Corrosion is induced using cyclic polarization per ASTM F2129, measuring the threshold the material can sustain before pitting corrosion propagates and the ability of the material to re-passivate, or terminate the corrosion reaction, when the driving voltage is reduced.
