(OP)
Question :
The theory is it true :
The parts with steel in very low carbone content (0.1 %) is more sensitive to gaz porosity of oxygene.
If we see this figure from the research publications: i want to say yes !
is it true ?
What is your experiences ?

The graph above illustrates the importance of controlling the amount (and time) of oxygen blowing during steel making practice. As the graph depicts, you can only reduce the carbon content to a certain point in liquid steel, where any further attempts in oxygen blowing results in an increase in the amount of dissolved oxygen that can form oxide inclusions.
If you can get access to a copy of ASM Handbook, Volume 1, there is an equilibrium curve for dissolved oxygen and carbon contents for various steel making practices (section titled Steelmaking). Also, there is a detailed explanation for removal of elements and increased temperature during oxygen blowing.

system and other elements commonly found like Mn or Si may not be present.
I have been producing low carbon steels in induction furnace .The carbon is 0.08max,Mn 0.5% and Si 0.35%. This is for an electrical application.
In case of stainless steels you make CF3M grades where the carbon is <0.03%.
However,the fact remains that with low carbon the metal tends to become gassy very fast.
