The test that is used to estimate the corrosion behavior of alloys in various environments is ASTM G61. We rely on our experience to assemble customized tests to simulate the service environment. We can predict pitting, crevice, general corrosion as well as stress corrosion cracking susceptibility of an alloy.

Calculating Corrosion Rate
Using a electrochemical technique (ASTM G59), we can calculate corrosion rates during events or under dynamic conditions such as temperature fluctuations and concentration spikes (or dips) during process conditions. By monitoring corrosion rates, we can help optimize process conditions or operating temperatures, or set minimum levels for corrosion inhibitors.

Evaluating Galvanic (Dissimiliar Metal) Corrosion
Galvanic corrosion is responsible for helping us see in the dark when we turn on a flashlight. When adverse galvanic corrosion occurs, we can use ASTM G71 to monitor the effects and make predictions of how well materials will "get along" under process conditions. We can recommend changes if dissimilar alloys do not provide adequate corrosion resistance.
