ASME SA387 pressure vessel plates is one of our popular products in our factory. IBC (Tianjin) Industrial Co., Ltd provide and export all sizes and thickness of pressure vessel steel plates to all over the world.
This specification covers chromium-molybdenum alloy steel plates intended primarily 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. Plates are available under this specification in several grades having different alloy contents as follows:
Supply Range of ASME SA387 Pressure Vessel Plates
- Standard: ASME SA387
- Grade: 2, 5, 9, 11, 12, 21, 22, 91, 911
- Delivery Condition: Annealed, Normalized, Quenched
- Size: 2000-2200mm x 6000-12000mm x 6 – 100mm
Each grade except Grades 21L, 22L, 91 and 911 is available in two classes of tensile strength levels as defined in the Tensile Requirements tables. Depending on heat treatment. In the annealed condition all grades are available only as Class 1. Grades 21L and 22L are available only as Class 1. Grade 91 and 911 are available only as Class 2.
The maximum thickness of plates limited only by the capacity of the composition to meet the specified mechanical property requirements. 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 use independently of the other. Combining values from the two systems may result in non-conformance with this specification.
The steel shall conform to the requirements as to chemical composition shown in Table 1. Unless otherwise modified in accordance with Supplementary Requirement S17, Vacuum Carbon-Deoxidized Steel, in Specification A20/A20M for grades other than Grade 11.
Plates are available under this specification in several grades having different alloy contents as follows: Each grade except Grade 21L, 22L, and 91 is available in two classes of tensile strength levels as defined in the Tensile Requirements tables. Grade 21L and 22L are available only as Class 1. Grade 91 is available only as Class 2.
The steel materials shall kill 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. It’s specimens shall also undergo tension tests and shall conform to the required values of tensile strength, yield strength, and elongation.
Tension Test Requirements —— The material as represented by the tension test specimens shall conform to the applicable requirements of Table 2 or Table 3. As specified on the order. Adjustment of the percentage elongation requirements is permitted in accordance with Specification A 20/A 20M for plates up to 3⁄4 in. [20 mm] inclusive, in thickness when an 8-in. [200-mm] gage length is used.
In addition to the marking required in Specification A 20/A 20M, each plate legibly stamped or stenciled, depending upon the ordered thickness, with the letter A for annealed, N for normalized and tempered, and Q for accelerated cooled and tempered, as applicable.
5.1 Except for Grades 91 and 911, all plateS thermally treated either by annealing, normalizing- and -tempering, or, when permitted by the purchaser, accelerated cooling from the austenitizing temperature by air blasting or liquid quenching, followed by tempering. Minimum tempering temperatures shall be as follows:
Grades 91 and 911 plates shall be normalized at 1900 to 2000°F [1040 to 1095°C] and shall be tempered at not less than 1350°F [730°C].
Grade 5, 9, 21, 21L, 22, 22L, 91 and 911 plates ordered without the heat treatment required by 5.1 furnished in either the stress-relieved or the annealed condition. For plates ordered without the heat treatment required by 5.1, heat treatment of the plates to conform to 5.1 and to Table 2 or Table 3, as applicable, shall be the responsibility of the purchaser.
