Corrosion of 434 Stainless Fibres in Hydrochloric Acid

Abstract:

The effects of concentration and temperature of hydrochloric acid and etching time on the corrosion rates of 434 stainless steel fibres are investigated by using weight loss method,The results show that with the concentration of hydrochloric acid increase,the temperature of hydrochloric acid rise, etching time prolonging, the corrosion rate of 434 stainless steel fibres is increased, and the corrosion rate of smalldimension of 434 stainless steel fibres faster.Though Cl- of hydrochloric acid doesn’t take direct part in the reaction,the corrosion rate is significantly accelerated.
