...-bolts fractured in fatigue because the bolt material had poor hardenability relative to the diam of the bolts. The bolt material was changed from 1045 steel to 1527 steel, a warm-finished low-alloy steel. The diameter of the bolts was reduced to 27.2 mm and the threads were rolled rather than cut...

... in the solution-annealed condition. 14 Modified alloy 439 compositions with low C contents are available that have improved formability and corrosion resistance. 2 The use of argon oxygen decarburization steel-refining practices makes low-C-content alloy 439 readily available. Welding is generally performed...

The microstructure was compatible with a steel which is cast, carburized, quenched, and tempered. The structure was generally satisfactory, except...

... investigation. Antimony, phosphorus, tin, sulfur, lead, and other low-melting-point impurities, which are generally very expensive to analyze, may be contributing to the embrittlement situation. These elements come from the raw steel and, similar to hydrogen, are more damaging when they are present in the grain...
