What Is Alloy Steel Plate ?
An ISO 9001:2008 Certified Company, GNEE Steel is a leading manufacturer and supplier of Cr Mo Alloy Steel Plates (ASTM A 387 Grade 11/22 Class 2). Aakash Steel stocks an extensive range of high quality alloy steel plates for manufacturing pressure vessels and industrial boilers for the petroleum, petrochemical and chemical processing industries. Two of the most popular pressure vessel steel grades include ASME SA 516 (ASTM A516) carbon steel and ASME SA 387 (ASTM A387) alloy steel. Thicknesses available in range from 3 mm up to as thick as 100 mm, although thicker plates might be manufactured under special order
ASTM A387 / A387M – Specification For Pressure Vessel Plates, Alloy Steel, Chromium-Molybdenum
This specification covers chromium-molybdenum alloy steel plates for welded boilers and pressure vessels designed for elevated temperature service. Materials considered under this specification are available in grades 2, 12, 11, 22, 22L, 21, 21L, 5, 9 and 91. The steel materials shall be killed and shall be thermally treated. The steel specimens shall undergo heat analysis and product analysis and shall conform to the chemical requirements for carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, nickel, vanadium, columbium, boron, nitrogen, aluminum, titanium, and zirconium. The steel specimens shall also undergo tension tests and shall conform to the required values of tensile strength, yield strength, and elongation.
