Alloy Steels Plates are metallic plates or sheets that are made from alloyed steels. An alloy is a mixture of elements together with steels.
Hi-tech Metal & Tubes is a manufacturer and supplier of different specifications, grades and types of steels plates. There are different alloying elements such as chromium, nickel, molybdenum, niobium, vanadium and titanium that make up the plate material. The Alloy Steels Plates are used for various applications. Transportation industry, oil and gas industry and many other domestic and industrial applications use these plates. One major use of the AS Sheet is that it could be used as cladding material to prevent corrosion on other metallic materials. The alloy sheets are also used to make tanks and storage containers. In addition to the sheets, we also manufacture and supply the AS Coil which is used in structural applications as well as high temperature services. There are different specifications such as the ASTM A387 Plate which have different applications. Our steels plates are made up of perfect quality steels and they abide by international standards. There are also the Low Alloy Steels Plates which are harder and have high wear and tear resistance. Please contact us for any of your alloy steel plate needs.
