To know heat resisting and sulphurizing properties of hot dipped steel material, several tests done were by heating that material in the air and in the hydrogen sulphide atomosphere, and after 5hrs heating, increase of the weight is measured.In case if the aluminizing is done with same fabricating condition, increase of the weight of the specimen is greater proportionally to the increase of carbon content in the steel.The proportion of weight increase of aluminized steel to that of base steel was ascertained as much as 30.3% in case of heating in the air and 10.3% in case of hydrogen sulphide.The time-weight increment curve is found to be parabolic.Several specimens, to know their corrosion properties, were tested to measure weight loss and electrode potential in the solution of sod. chloride, dil. sulphuric acid and sod. hydroxide.Corrosion resistance was found excellent in 3% and 10% of sod. chloride solution, as well as in 1/1000mol sulphuric acid solution. In the solution of hydroxide, Fe-Al layer well protects effectively the base steel material.
