Our Analytical Lab also employs Optical Emission Spectrometry (OES or Arc Spark) for routine analysis of metals and their alloys. The OES has been designed specifically to meet the demands of quality assurance in the metal production and metal testing industries. OES technology is used for quick turnaround analysis of Iron, Aluminum, Cobalt, Titanium, and Nickel-based alloys.
Carbon, Sulfur, Hydrogen, Oxygen, and Nitrogen content in steel and titanium is determined by the inert gas fusion thermal conductivity method (ASTM E1019 and ASTM E1447) utilizing Leco instrumentation.
The analytical section has the capability to run various corrosion tests. The susceptibility to intergranular corrosion in wrought, nickel rich, chromium bearing, and stainless steels is detected using ASTM methods G28 and A262. Our environmental test unit is utilized for modified salt spray and copper-accelerated salt spray testing (ASTM G85 and ASTM B368). Pitting and crevice corrosion (ASTM G48) and Stress corrosion cracking in boiling magnesium chloride solution (ASTM G36) are among the other corrosion tests that can be performed.
The ASTM B117 Salt Spray Test is used to determine normal corrosion resistance to ocean water type environments. The ASTM B368 (CASS Test) is widely used to evaluate aggravated conditions such as road salt on automotive parts.
Typical materials analyzed include:
