Compare the TTT diagram of 1018 and 4340. Difference??

[eric56hk]

Compare the TTT diagram of 1018(A36) and 4340. What are the major differences? Why does the decomposition of austenite take longer in 4340 than 1018 (A36)???

Where can I find a TTT (isothermal transformation diagram) for 1018(A36) steel?? I can only find a 1019 TTT(the closest)

Pleas help!!!!...Thanks!

Read the effect of alloying elements on TTT curve in any physical metallurgy book or ASM handbook. This will provide you an insight on the transformation curve and products.

There will be no difference between 1018 and 1019.

Here is a source of diagrams:
