2.25Cr-1Mo steel plate meaning and application

2.25Cr-1Mo, 2.25Cr means that the content of Cr is about 2.25, that is, about 2250. Therefore, 1Mo means that the content of Mo is about 1, that is, about 1000. 2.25Cr-1Mo steel plate is a chromium molybdenum steel, a low-alloy high-strength steel, which belongs to heat-resistant alloy steel, also known as SA387 Gr22 CL2 or A387 Gr22 CL2.

2.25Cr-1Mo steel plates are widely used in hot wall hydrogenation reactors, and have been in service for a long time under the harsh environment of high temperature (375~575 ℃), high pressure (6.9~28 MPa), and hydrogen (H2, H2S).
