The engineers at Reksolindo have an interesting inquiries for failure analysis suffered by different parts of equipment lately. Quitely different operation condition (high temperature and ambient temperature, medium and low carbon steel, marine atmosphere versus caustic feed water). We are really satisfied for microscopy works that can catch the clear picture of lightning type-branched small crack surrounding opening tip of main cracks below. The lightning type and branched of small cracks which are believed in many literature [1,2,3]as the finger-print of stress corrosion cracking mode. And it was very clueful which made us more easier to find the contributing causes .
1. Chloride-SCC in an uncoated medium carbon steel bolt in marine atmosphere
2. HAZ – Caustic SCC at 100-250 °C
Stumble It!
