Multi Metals is a respected manufacturer, distributor, and stockiest of Duplex Steel & Super Duplex Steel Plates, Sheets, Shims, Coils, and Foils in South Africa. We provide a wide range of Super Duplex Steel Plates in different specifications, sizes, types, dimensions, and specifications in South Africa. We design these products using superior quality raw materials and modern technology under the guidance of a professional team. Duplex Steel Alloys are used extensively because they offer immunity from chloride stress corrosion cracking, thermal conductivity and has a low coefficient of thermal expansion as well.
We provide Duplex Steel Plates in a different type of thickness, specification, grades and dimensions. We also offer these duplex steel plates in all sizes such as ASTM A240 / ASME SA240. They are the non-ferrous metals with higher strength and robustness, excellent resistance to corrosion, and high temperature. The Super Duplex Steel Plates finds their applications in basic industries such as Sugar, Paper, Textile, Dairy, as well as in complex industries like Oil & Gas Industry, Petrochemical Industry, Chemical & Fertilizers, Power Generation Industry and Nuclear Industries.
These Duplex Steel Plates have a tensile strength of 138000 PSi, 950 MPa whereas yield strength of 128000 PSi, 880 MPa. They have an elongation of 14% and a melting point of 1632 degree Celsius. The Super Duplex S32750 coils are used especially in improving gas-based technology, oil production, oil industry equipment and many more. These duplex sheets have excellent specifications and exceptional resistance to the crevice and pitting corrosion with another chloride including atmospheres. Our Duplex Steel UNS S31803 sheets also demonstrate higher heat conductivity and pose a low coefficient of thermal growth and are well-suited for temperature up to 300 degrees C.
Duplex Steel UNS S31803 Foils, Coils, and Shims have high thermal conductivity, excellent resistance to chloride stress corrosion cracking, and a low coefficient of thermal expansion. The high chromium, molybdenum and nitrogen levels provide excellent resistance to pitting, crevice and general corrosion and they also have a high impact strength.
