Shashank Stainless is a proven manufacturer and a supplier of Dubai, UAE quality stainless steel-based products. Sustained by core values of reliability and customer care, we render a wide scale of stainless solutions to various types of industries-from automotive to constructions and manufacturing industry. Our Stainless Steel 309H sheets and plates have been specially made to be corrosion resistant and perform well in hot conditions and environments. These applications are mostly done in furnaces, heat exchangers, and chemical processing. With higher resistance to oxidation and corrosion, our products have longer performance life and durability while satisfying the local and international industrial standards.
Stainless Steel 309H is an austenitic stainless steel alloy offering high resistance against oxidation and has excellent strength up to high elevated temperatures. Typically, it consists of about 24-26% chromium, 12-22% nickel, and balance iron. Material offers good weldability, formability, corrosion resistance, mainly in high temperature environments. Mechanical properties Stainless Steel 309 contains tensile strength of nearly 515 MPa, a yield strength around 205 MPa, and elongation to the breaking point nearly about 40%. It has widely been employed in furnace elements, heat exchangers, and chemical process equipment due to its superior hot resistance and longevity.

Due to excellent corrosion resistance, these sheets are manufactured at very high temperatures. Mechanical properties are improved by that manufacturing process. They are available with thicknesses in range of 3 mm up to 50 mm and width up to 2000 mm for structural and industrial applications.
The cold rolled plates were produced at room temperature with a polish finish. The plates come in various thicknesses from 0.5 mm to 6 mm and widths as much as 1500 mm making it very ideal for precision and aesthetic purposes.
These plates offer excellent corrosion resistance and a textured surface for improved grip and slip resistance. They are usually available in thicknesses from 3 mm to 10 mm and dimensions up to 2000 mm x 1000 mm, and are used in flooring and safety applications.
The perforated sheet has strong resistance to corrosion with various hole patterns for functional as well as for aesthetic purposes. Sizes are commonly between 0.5 and 6 mm in thickness, and up to 2000 mm x 1000 mm in dimensions to be used in filtration and ventilation.
These thin sheets give good corrosion resistance and are applied to spacing and levelling accurately. The availability is as thin as 0.1 mm, with up to 1000 mm width. These sheets are of crucial use for aligning machinery and construction work.
Polished plates offer excellent resistance to corrosion with a highly reflective finish through polishing. They have thicknesses in the range of 1-20 mm, and their dimensions could go up to 2000 mm x 1000 mm, commonly being used in decoration and architecture applications.
Shashank Stainless is a leading supplier and stockist of high-quality stainless steel 309H sheet and plates in Dubai, UAE. Our products are widely used in various applications, and we are committed to delivering excellent service, resulting in high customer satisfaction. Our unique finishing techniques further distinguish us in the stainless steel industry. We are dedicated to consistently providing superior products and effectively meeting our customer’s needs.
Stainless Steel 309H sheets and plates are used for high-temperature applications due to their excellent oxidation resistance and strength. It is used in parts of heat exchangers, furnace parts, and kilns since the material is strong and resists scaling at elevated temperatures. It is also used in chemical processing equipment such as reactors since it has good corrosion resistance in aggressive environments. Some other applications include boiler parts, incinerators, and flue-gas stacks. It can be used for manufacturing machinery, where it has to withstand extreme heat, in the aerospace, power generation, and petrochemical industries.
