Materials supplied under SA204MGrA in accordance with this standard shall meet the requirements of the A20/A20M standards. These requirements include the methods and procedures for testing and re-inspection, allowable tolerances for size and weight, correction of defects and quality issues, marking, and loading. I. SA204MGrB material and manufacturing: Steelmaking process—the steel should be a killed steel. Delivery condition of SA204MGrB: Steel plates with a thickness of ≤40mm are usually supplied in the rolled state; they can also be supplied after normalizing or after a combination of normalizing and stress relief treatment. II. Steel plates with a thickness > 40 mm should be normalized. III. SA204GrB is produced in accordance with ASME (American Society of Mechanical Engineers) standards by Wuhan Iron and Steel Group; it offers the highest quality. It is widely used in industries such as petroleum, chemicals, power generation, and boilers, for manufacturing equipment and components including reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, pressure vessels for nuclear reactors, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes in hydroelectric stations, and turbine casings. The available steel plate specifications range from 8 to 700 mm in width, 1500 to 4000 mm in length, and 3000 to 12000 mm in height. We can also supply various types of cut parts, flanges, and custom-shaped components as per the customer’s requirements – all you need is a drawing; leave the rest to us. Our professional processing team is sure to meet your expectations. Steel plate packaging: shipped bare, with a steel stamp printed 500 mm from the end of each plate, including the steel grade, furnace number, and batch number. Mark the factory logo, dimensions, steel grade, furnace number, and batch number on the surface of the steel plate using a stamping die. Each steel plate should also be clearly marked with the delivery condition, such as N (normalized) or N+T (normalized + tempered), according to the order given. SA204 is divided into three levels: A, B, and C
