  organization structure:

  After solid solution at 1200 ℃, it is basically single-phase austenite and a small amount of MC and M23C6 type carbides. After long-term aging at 700-900 ℃. There is little change in MC, and M23C6 is distributed in a chain like manner at grain boundaries. With the increase of aging time, the precipitation amount increases and the particles grow; At the same time, WCr solid solutions are added and precipitated within the grain and at the grain boundaries, appearing in granular form. With the extension of aging time, the quantity gradually increases and the size continues to grow. According to relevant technical standards, the grain size of cold rolled sheet in supply state should be within the range of 4-8 levels.
