초록

Effect of boron on corrosion resistance of Type 304 stainless steel has been studied. Boron tends to segregate at the grain boundaries during cooling after solution treatment, and so boron treated steel usually exhibits a ditch structure under the 10% oxalic acid test. However, it was found that the addition of 25 ppm boron in Type 304 steel has no effect on the general and pitting corrosion resistance while it has a little effect on the intergranular corrosion resistance.
