We produce ASME SA203 Pressure Vessel Plates according to the Standard Specification for Pressure Vessel Plates, Alloy Steel, Nickel. IBC Metal Group produce & export all kinds of pressure vessel plates to all over the world.
SA203 steel grade is a nickel alloy steel plate in welded pressure vessels. For this standard the max thickness in 150mm and the element of nickel is 2.25% to be used in manufacturing pressure vessel and boilers. We use in fabricators serving industry, especially in the oil, gas and chemical supply markets.
Supply Range of ASME SA203 Pressure Vessel Plates
- Thickness: 6MM to 150MM,
- Width: 1500mm to 4050mm,
- Length: 3000mm to 15000mm
The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements. However, current practice normally limits the maximum thickness of plates furnished under this specification as follows:
| Grade | Maximum thickness, in. [mm] |
|---|---|
| A | 6 [150] |
| B | 6 [150] |
| D | 4 [100] |
| E | 4 [100] |
| F | 4 [100] |
The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents. Therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.
Chemical Composition of ASME SA203
The steel shall conform to the chemical requirements shown in Table 1 unless otherwise modified in accordance with Supplementary Requirement S17, Vacuum Carbon-Deoxidized Steel, in Specification A 20/A 20M.
Tensile Requirements
Tension Test Requirements—The material as represented by the tension test specimens shall conform to the requirements shown in Table 2. For plates that have been heat treated in accordance with 5.1.1.1 or 5.1.2 and have a nominal thickness of 3⁄4 in. [20 mm] and under, the 11⁄2-in. (40-mm) wide rectangular specimen may be used for the tension test, and the elongation may be determined in a 2-in. [50-mm] gage length that includes the fracture and that shows the greatest elongation. When this specimen is used, the elongation shall be not less than 23 %.
Material supplied to this material specification shall conform to Specification A20/A20M. These requirements outline the testing and retesting methods and procedures, permissible variations in dimensions and mass, quality and repair of imperfections, marking, loading, etc. Specification A20/A20M also establishes the rules for the basis of purchase that complied with when purchasing material to this specification.
