Without these precautions, carbon steel pressure components are likely to be vulnerable to brittle fracture during hydrotesting or during operation, even when operated at or below 60 degrees F. WebBrittle fractures are characterised as having little or no plastic deformation prior to failure. Materials that usually fracture in a brittle manner are glasses, ceramics, and some polymers and metals. Under some circumstances some metals that are usually ductile will fail in a brittle manner, possibly with catastrophic results. clearview risk management
