METHOD FOR PREVENTING HYDROGEN EMBRITTLEMENT

摘要

PROBLEM TO BE SOLVED: To provide a method for preventing hydrogen embrittlement of a steel material such as high strength steel.SOLUTION: Bacterial flora 102 including yeast is stuck onto the surface of a steel material 101 to increase the potential on the surface thereof to suppress a reduction reaction on the surface thereof. Yeast may be stuck onto the surface of the steel material together with water. Yeast may be at least one selected from MT8-1 and BY4741. Such yeast proliferates by itself in the natural environment.
