Titanium is revered for its strength-to-weight ratio and corrosion resistance. However, when we introduce the "ECM" variable—whether referring to Electrochemical Machining or a specific grade of ultra-fine grain titanium—engineers face a persistent enemy: hydrogen-induced cracking (HIC) and stress corrosion cracking (SCC) .
If you are experiencing cracking, stop blaming the base alloy. Instead, audit your , measure the hydrogen content of your reject parts, and implement a vacuum baking cycle. Without these steps, ECM Titanium will remain a brittle hazard rather than a high-performance asset. Disclaimer: This article discusses general engineering principles. Always consult the specific material datasheet for your "ECM Titanium" grade (e.g., Grade 23 ELI vs. Grade 5) as hydrogen tolerance varies significantly.
