Located in the bustling industrial heart of Cairo, Egypt, Khaled Stainless has built a reputation as a trusted manufacturer and supplier, particularly known for their expertise in high-performance materials. Their offering of Stainless Steel 309H Sheets and Plates is a prime example of their commitment to quality. This premium grade is specifically engineered to excel in demanding, high-temperature environments, making it an essential resource for industries throughout the region that require unmatched durability and heat resistance.
The impressive performance of 309H stems from its carefully balanced composition, which includes higher levels of chromium and nickel for superior oxidation resistance. This is further enhanced by its controlled carbon content, which gives it excellent strength and creep resistance when exposed to sustained high heat. These inherent material properties translate into sheets and plates that maintain their structural integrity, resisting warping or degradation even under the most thermally stressful conditions.

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.
