ATM standard of 4340 steel
Dear sir,
I am currently doing a project on "The effect of hydrogen charging on tensile properties of high strength steel, grade 4340".......so I want to know what is the specific ASTM standard which gives information regarding hydrogen embrittlement of 4340steel.

Hello Janardhan!
I have to assume that you are familiar with the work of A.R. Troiano, who wrote a lot about this topic in the 1950's, and published in Transactions of the AIME. Given that, you'll want to examine ASTM volume 15.03, which has a number of specifications for testing for hydrogen embrittlement. ASTM F519, for example, assumes that air melt 4340 is the worst case material and uses material per Mil-S-5000 for its test samples.
Good luck!
