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. ecm titanium crack
