Fatigue Fracture Of A 300M Ultra-high Strength Steel Race Car Transmission Input Shaft Summary: A fractured input shaft used in NASCAR racing was received for analysis to investigate the cause of failure. Results indicate the shaft fractured due to fatigue progression from an intergranular stress crack, initiated at a dot peen identification marking on the […]


Pitted Still Condenser Tubes

Posted on April 6th, 2016 by Met-Tech

Share This Case Study:

Failure Analysis of Pitted Still Condenser Tubes SUMMARY: Several concentrating still condenser tubes exhibiting pitting were received to determine the cause of pitting. Results indicate the tubes pitted initially from the inner diameter (ID) surface due to microbiological corrosion (MIC). MIC pitting initiated preferentially at the tube seam weld. Additional ID surface pits and significant […]
