The Stainless Steel 309H sheets and plates produced by Ed Stainless in Texas are primarily made of iron, featuring a high chromium content of around 23% and nickel content of about 13%, which gives them excellent oxidation resistance. The “H” signifies a higher carbon content, enhancing their strength at elevated temperatures. This alloy boasts a tensile strength of roughly 75 ksi, a yield strength close to 30 ksi, and an elongation of around 40%. These mechanical properties allow it to handle thermal cycling and stress without warping, making it perfect for extreme conditions while maintaining its structural integrity under high temperatures.

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.
