Wah Chang has a well-equipped corrosion testing laboratory designed to generate new corrosion data on our products and to assist in customer evaluations of media and materials. This laboratory is available for immersion, electrochemical, high temperature autoclave, and stress corrosion testing. Velocity effects can also be studied. Testing equipment includes electrochemical systems for

• cyclic polarization
• linear polarization
• galvanic coupling and AC impedance studies
• a slow strain rate Stress Corrosion Cracking (SCC) testing machine
• autoclaves capable of withstanding severe corrosives at pressures to 500° psi and temperatures to 250° C
• sufficient immersion testing equipment to perform 200 simultaneous immersion tests.

Diagnostic equipment includes a Zeiss metallograph, a scanning electron microscope with EDAX capabilities, an electron microprobe and the services of our Analytical Laboratory, one of the finest in the world. On-site analytical capabilities include:

• emission
• mass and atomic absorption spectroscopy
• x-ray fluorescence diffraction ¥ classical wet chemistry and interstitial gas analysis.

Wah Chang also offers complimentary corrosion coupons for customer laboratory or in-plant testing.
