ASTM A 387 GRADE 11, 12,22,5,9, CLASS-2 |
| 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, 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.Physical Properties |
ASTM A387 grade steel plates are intended for welded boilers and pressure vessels designed for
elevated temperature environments.
