What is the difference between 1Cr5Mo and Cr5Mo?

When examining the material of the heating furnace tubes in the two atmospheric-pressure units, what are the differences between the tubes made of 1Cr5Mo and Cr5Mo materials?
The carbon content varies. 1Cr5Mo has a higher carbon content than 0Cr5MO, so it possesses higher strength but lower elongation.
