Stronger doesn’t always mean safer – Hydrogen Embrittlement

Stronger doesn’t always mean safer – Hydrogen Embrittlement

As hardness increases — particularly above ~35 HRC — susceptibility to hydrogen embrittlement can rise significantly, leading to: ❌ Delayed cracking ❌ Sudden brittle failures ❌ Unexpected component breakdowns ⚠️ Stronger doesn’t always mean safer. One critical mechanism often overlooked? 🔬 Hydrogen Embrittlement When designing high-strength components, choosing the highest hardness material may unintentionally increase […]

Failure Analysis of Thread Damage

Failure Analysis of Thread Damage

In industries like oil & gas, improper thread design or damage in collar-box connections can lead to operational downtime, safety risks, and costly equipment failure. Similarly, in fastener applications, compromised threads can result in loss of structural integrity.   Why Thread Engagement & Tolerance Matter Proper thread engagement length ensures load distribution across multiple threads, […]
