S-TEN Plate

Supplier of S-TEN 1 Sulfuric Acid Dew Resistant Steel Plate in India at best price

Industrial processing and flue-treatment systems at low temperatures have become a major hurdle. The S-TEN Plate resists the formation of corrosion induced by sulfuric acid in this reducing media. These plates have excellent strength and don’t easily dissociate under any pressure. A s ten plate or the Sulfuric Acid and Hydrochloric Acid Dew-Point Corrosion-resistant steel plates can be produced in hot or cold rolling processes. These plates have good stability and torsion across different stress-induced setups.

The S-TEN Steel Plate has outstanding workability and can be welded in place easily. These plates offer an economical option over stainless steel components. The Sulfuric Acid Dew Resistant Steel Plate is a common feature in low-temperature flue gas treatment equipment. These plates are a feature in automobile industries, coal-fired boilers, fabrication, pumps, machine building, oil and gas systems, etc.

One of the best applications of these components is in the field of thermal power generation and waste incineration plants. The versatile grade of products can be custom designed in different shapes and sizes as per your project requirements.

The S-Ten plate is designed in two grades, with the S-TEN 1 Plates being highly resistant to hydrochloric acid dew point corrosion as well as sulfuric acid dew point corrosion. In contrast, the S-TEN 2 Plate only shows resistance against sulfuric acid dew point corrosion in the system.
