We specialize in stainless steel sheets and plates – 321/321H with an aim towards excellence in delivering the products across industries. All our products show great durability and resistance to corrosion with precision. Top quality and on-time delivery are always guaranteed, hence we are always a reliable partner in the UAE and worldwide.
Austenitic Stainless Steel 321/321H is titanium alloyed to enhance resistance to intergranular corrosion. The material contains 17-19% chromium, 9-12% nickel, and the titanium content is 5 times the carbon content to stabilize it. The grade 321H has a higher carbon content to provide improved high-temperature strength. It has excellent resistance to oxidation and corrosion and is excellent at elevated temperatures up to 900°C or 1650°F. It has excellent weldability, formability, and machinability, so is well-suited for heat exchangers and pressure vessels chemical processing.

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.
Shashank Stainless offers an excellent customer experience along with detailed documentation of its high-quality Stainless Steel 321/321H Sheets and Plates. We deliver key documents such as the commercial invoice, packing list, fumigation certificate, heat treatment chart, quality assurance plan, and NABL-approved lab test report, making it easier to validate the authenticity and superior quality of our products for the value-added customers. Our Stainless Steel 321/321H Sheets and Plates, meanwhile, possess diversified test certificate features, ranging from MTC accordance with EN10204 /3.1B to a PMI test Certificate, radiographic test reports having 100 % and even up to third Party Inspection. Here, too the certificates explain their customer-driven activities and unwearied product quest for superior product quality.
SS321/321H sheets and plates are widely used in high-temperature applications, mainly because they posses very good resistance against oxidation and intergranular corrosion. SS321/321H sheets and plates are suitable for heat exchangers, pressure vessels, boilers, and manifolds in chemical and petrochemical industries and power generation. It is also used for exhaust systems, furnace parts, and aircraft engine parts since it does not degrade the strength and stability up to high temperatures.
