S Ten Sulfuric Acid and Hydrochloric Acid Dew-Point Corrosion-Resistant Steel Plates, Sulfuric Acid Dew Resistant Steel S-TEN Plates, S-TEN Plates Exporters, S-TEN Plates Suppliers and Stockists in India.
Champak Steel & Engg.Co is a notable supplier and exporter of S-TEN Plate in Mumbai, India. S-TEN demonstrates the greatest resistance to sulphuric acid and hydrochloric acid dew-point corrosion found in flue gas treatment equipment used in coal-fired boilers, waste incineration plants, etc. S-TEN is cheaper than stainless steel. S-TEN has comparable strength, workability and weldability to ordinary steel.
S-TEN Plate offers a wide range of products, from hot-rolled sheets (plates), cold-rolled sheets, pipes and tubes to welding material. S-TEN 1 is efficiently resistant to both sulphuric acid dew point corrosion and hydrochloric acid dew point corrosion, whereas S-TEN 2 has effective resistance to sulphuric acid dew point corrosion. These S-Ten Plates are used in tall smokestacks, air preheaters, electrostatic precipitators and flue-gas desulfurizers, etc. We also supply these S-Ten Plates in various sizes, dimensions, and thickness and also as per the custom requirements of the clients at reasonable prices.

Application Examples for S-TEN
Equipment | Practical application examples | Precautions in use | |||
---|---|---|---|---|---|
Application | Grade | Approximate plate thickness (mm) | |||
S-TEN 1 | S-TEN 2 | ||||
Dry-type electrostatic precipitator | Casing, duct, collecting electrode | ○ | ○ | 1.2~8 | The temperature of casings and ducts is 20~70℃ lower than that of flue gas, depending on the heat insulation conditions. It is estimated that the temperature of the collecting electrode and the gas is the same. In cases when dust accumulates, the absorbed H2SO4 is difficult to evaporate and leads to cases of more than expected corrosion. As a result, it is necessary to prevent dust accumulation. |
Wet-type electrostatic precipitator | Casing, duct, collecting electrode | ○ | ○ | 3.2~12 | In cases when the flow of scrubber water is constant against a wall surface, the corrosion mass increases (by 0.1 mm/yr on one side). Further, in cases when the scrubber water in such a situation has a low pH value, the corrosion mass will increase abruptly, thereby making it necessary to avoid the use of S-TEN. |
Gas cooler | Casing, duct | ○ | ○ | 4.5~9 | The temperature of casings and ducts is 20~70℃ lower than that of flue gas, depending on the heat insulation conditions. The mist droplet becomes large due to the deterioration of nozzle holes and does not evaporate to reach the casing, under which there are cases when unexpected corrosion occurs, and thus it is necessary to control the deterioration of nozzle holes. |
Ash discharge blade | - | ○ | 12~20 | S-TEN 2 is most suitable for use as the material for the blades that discharge the ash accumulated in the bottom section of gas cooler. The stress-induced corrosion cracking attributable to the chlorides contained in the ash can be prevented from occurring. | |
Air
preheater |
Ljungströmtype basket case, element | ○ | ○ | 0.6~6 | Because of repeated fluctuations in wall surface temperature, dew-point corrosion from high to low temperatures occurs repeatedly, and the application advantage of S-TEN is exhibited to the high degree. |
Tube | ○ | - | 0.6~3.5 | The tubes are constantly in the dew-point state, and accordingly, S-TEN is highly effective. S-TEN 1 tube is most suitable for such application. | |
Flue | Duct, expansion | ○ | ○ | 4.5~9 | S-TEN of the no coating specifications or the acid resistantcoating specifications is suitable. When the temperature of the flue gas itself drops below the dew point, drainage accumulates in the flue bottom, frequently causing unexpectedly severe corrosion, and thus it is recommended to provide appropriate measures to carry out sufficient drainage and to prevent lowering of steel plate temperatures by means of external heat insulation. |
Stack | Internal cylinder | ○ | - | 6~12 | |
Flue-gas desulfurizer | Flue-gas cylinder, after-burner duct | ○ | ○ | 3.2~6 | In the ducts leading to and from gas coolers and absorption towers, low pH solutions occasionally adhere to wall surfaces due to sulfuric acid mist, and therefore it is necessary to fully investigate drainage conditions. |
Hydrochloric acid pickling tank | Tank | ○ | - | 9~20 | The use for hydrochloric acid pickling tank in coating is suitable. S-TEN tanks have a high scratch resistance during use, and these tanks after use can be treated as the general recyclable steel material. |
