The phosphorus in the iron and steel gives most injurious effect on their properties as well as sulphur, so that it is encouraged to eliminate the phosphorus as lower as possible in their manufacture. There are many literatures as to the effects of phosphorus on the mechanical properties of steel, but as its effects change by the amount of carbon and other impurities in it, it is impossible to specify the limit of phosphorus content which is not objectionable to the properties of steel, and also it is impossible to express the change of mechanical properties by the increase of phosphorus content. The author made the phosphor-irons which contain the phosphorus from 0.014 to 0.91 per cent with very small amount of carbon and other impurities, and he investigated the effect of phosphorus on the mechanical and physical properties of iron.
