Khaleed Stainless is a reputable manufacturer and supplier based in Riyadh, Saudi Arabia, known for providing top-notch Stainless Steel 321/321H Sheets and Plates. These products are crafted for durability, strength, and long-lasting performance, making them perfect for critical industries. You’ll find these sheets and plates commonly used in sectors like petrochemical, oil and gas, chemical processing, heat treatment, and power generation, where high-temperature resistance and corrosion protection are a must. With precision manufacturing that meets international standards, Stainless Steel 321/321H Sheets and Plates offer outstanding reliability, workability, and longevity in tough environments.
These sheets and plates are mainly made up of iron, chromium (17–19%), nickel (9–13%), and titanium, which helps stabilize the alloy against carbide precipitation during welding. The Grade 321H, which has a higher carbon content, provides improved creep strength and better performance at elevated temperatures compared to the standard 321. In terms of mechanical properties, they boast a tensile strength of 515–570 MPa, yield strength of 205–240 MPa, and good elongation, ensuring they remain tough, thermally stable, and reliable under high mechanical and thermal stress.

These sheets contain high corrosion resistance and are available up to 1.2-12mm thickness and width up to 2000mm. They are ideal for high temperature application.
Cold rolled plates of SS 321H possess higher corrosion resistance and are available up to 0.3-6mm in thickness and up to 1500mm in width. They are perfect for applications requiring a smooth finish and high strength.
These plates provide outstanding resistance to corrosion, and come in thickness from 3mm up to 12mm and have sizes of up to 1500mm x 3000mm. Raised pattern surface increases the gripping value, thus commonly used for floor and structural work.
Perforated sheets are extremely resistant to corrosion and can be perforated from 0.5mm up to 20mm in diameter. The sheet thickness is also from 0.3mm up to 3mm. It is used in filtration and ventilation systems.
Shim sheets are resistant to corrosion with a high accuracy level. Thickness is available between 0.05mm up to 3mm, and cut-to-size service is also possible to get precise dimensions for several alignment and spacing applications.
Polished plates have excellent resistance to corrosion, and a reflective finish. These plates are manufactured in thickness range from 3mm to 50mm. The size for these plates up to 2000mm x 6000mm is ideal for aesthetic applications as well as a high-quality surface finish.
