MERIH STAINLESS, based in Istanbul, Turkey, stands out as a top manufacturer and supplier of premium stainless steel products. Their Stainless Steel 309H Sheets and Plates are crafted specifically for high-temperature applications, boasting remarkable strength, durability, and resistance to corrosion. Built to meet international standards, these sheets and plates offer precise dimensions, a smooth surface finish, and dependable performance even in extreme conditions. Perfect for industries like chemical, petrochemical, furnace, and power generation, MERIH STAINLESS 309H sheets and plates are designed for fabrication, forming, and welding, providing robust, maintenance-free solutions where long-term reliability is essential.
Stainless Steel 309H Sheets and Plates are primarily made up of iron, chromium, and nickel, featuring a higher carbon content than 309 to boost tensile and creep strength at elevated temperatures. In terms of mechanical properties, they showcase high tensile and yield strength, impressive hardness, and good ductility and toughness, making them easy to fabricate and weld without sacrificing structural integrity. This alloy excels in resisting oxidation, scaling, and corrosion, especially in high-temperature and chemically aggressive settings. These characteristics ensure that 309H sheets and plates remain durable, stable, and perform well under extended high-temperature use.

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.
