Plates are available under these specifications in several grades each having different nominal Chromium (Cr) and Molybdenum (Mo) contents as follows:

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.
