We provide high-strength, low-alloy steel plates for use in structures like buildings and bridges. These structural steel plates offer resistance to atmospheric corrosion and, subsequently, longer life in applications where exposure to the elements will be an issue. To meet the customers' individual needs, we provide our range of structural alloy plates in various sizes and thicknesses.
Chromium Molybdenum Plates, Alloy Steel Sheet Supplier, ASTM A387 Alloy Steel Plates, AS Sheet Plates, Cr-Mo Plate Manufacturers, Alloy Steel Plate Supplier in Mumbai, India.
Different steel grades and chemical compositions are used to make high-strength steel plates. High-strength plates are produced after the plates are deformed in the last step at specific temperatures. Alpha Overseas is a top manufacturer and supplier of high-tensile strength steel plates in various sizes and grades. Also, the minimum yield strength for the high-strength plate range is roughly 500MPa. The thickness of the plates is up to 80 mm. The shipbuilding, offshore oil drilling, and bridge construction industries are where the S420MC high-strength steel plates are used the most.
Various grades are available, including S420M, S460M, S460Q, S500Q, 550Q, 620Q, and many more. The minimum yield strength values for the s355j2n high-strength steel plate and other types vary, ranging from 365 MPa for thicker plates over 100 mm to very high yield strengths of up to 1150 MPa for high grades like S960Q with thinner plates under 50 mm. High-strength applications that require corrosion resistance and toughness might use the S1300ql High Strength Steel Plates. Niobium, titanium, nickel, molybdenum, copper, vanadium, chromium, and boron are all components of the material, along with carbon, silicon, manganese, phosphorus, and sulfur.
For example, the DILLIMAX 1300 High Strength Plates differ in their composition from other grades in that they are designed to have specific mechanical and physical characteristics. Cold cracking may appear in the material. S690QL1 High Strength Steel Plates can be warmed to the proper temperatures for various grades and thicknesses ranging from 30 mm to 130 mm from 75 degrees Celsius to 150 degrees Celsius to prevent cold cracking. Sailma 350 High Tensile Structural Steel Plates is one of the many names these steel plates are known by.
