High corrosion resistance and are available up to 1.2-12mm thickness and width up to 2000mm. They are ideal for high temperature application.
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.
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.
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.
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.
These Stainless Steel 321/321H Sheets and Plates find extensive use in industries that require outstanding oxidation resistance and thermal stability. You’ll commonly see them in heat exchangers, boiler components, furnace parts, jet engine components, exhaust manifolds, and chemical processing equipment. They’re also utilized in refineries, power generation, and aerospace sectors due to their ability to maintain strength and resist scaling at elevated temperatures. The exceptional corrosion and creep resistance of these alloys make them ideal for long-term use in environments that involve heat and aggressive chemicals.
Kyaw Stainless furnishes test certificates such as Mill Test Certificates (MTC) according to EN 10204 3.1 in order to certify the authenticity of materials and quality to industry requirements. The sheets and plates are well-packed wooden crates, plastic wrapped, or carton box-covered to eliminate damage during transport. With proper supply chain distribution, Kyaw Stainless makes timely deliveries across the world and meets high-pressure industrial requests with precision and respect.
