... Abstract Ball joints made from carburized En 353 (BS970:815A16) steel failed after several hours of being fitted into vehicles. The parts were forged, machined, and thread rolled. The threads were copper plated to prevent carburization. The heat treatment consisted of carburizing in a cyanide...

... fatigue. Crack propagation occurred either by corrosion or mechanical fatigue. Evidence was found indicating high rotary bending stresses on the shaft during operation. The nonstandard composition of the En 8 steel used in the shaft and irregular maintenance reduced the life of the shaft. Recommendations...

... by the corrosion process to produce insoluble black iron sulfide. Traditional models for predicting MIC in liquid pipelines in the oil and gas sector made the presence of iron sulfide at significant concentrations (>10 μg/cm 2 ) on the steel surface a prerequisite for MIC ( Ref 24 , 25 ). In waters where...
