S-TEN1 in hydrochloric acid pickling tank for plating and steel processing.
S-TEN1 for hydrochloric acid environments. Selection of base material that utilizes the scratch resistance of the tank body and the workability equivalent to ordinary steel.
In the hydrochloric acid pickling tank of the plating and steel processing line, the tank body is corroded by hydrochloric acid solution, steam, and splashes. While resin lining offers high corrosion resistance, issues can arise with scratches from incoming materials and fixtures, repairs, and sorting during disposal. We propose S-TEN1 as an option to reconsider from the perspective of the base material of the steel tank. S-TEN1, which is resistant to hydrochloric acid dew point corrosion, is used in the tank body of hydrochloric acid pickling tanks in applications by Nippon Steel. Cutting, bending, and welding can be handled with the concept equivalent to SM400A, and by using dedicated welding materials, the welded areas can also achieve corrosion resistance equivalent to the base material. However, S-TEN1 is not universally applicable to all concentrations and temperatures of hydrochloric acid. Selection should be made by confirming the liquid composition, temperature, flow rate, and whether it is immersion, steam, or splash.
