Grade | Nominal Cr Content (%) | Nominal Mo Content (%) |
2 | 0.5 | 0.5 |
12 | 1 | 0.5 |
11 | 1.25 | 0.5 |
22, 22L | 2.25 | 1 |
21, 21L | 3 | 1 |
5 | 5 | 0.5 |
9, 91 | 9 | 1 |
Each grade except Grades 21L, 22L, and 91 is available in two classes of tensile strength described as Class 1 and Class 2. The most regularly specified grades and hence those that are most readily available from stock are Grades 12, 11, 22, 5, and 9 and in most case stock plates will be produced to the tensile requirements of Class 2.
