Meaning of .3 in DIN1681 materials

Meaning of .3 in DIN1681 materials

Meaning of .3 in DIN1681 materials

(OP)
Hello all,

could some standard expert explain to me, what does .3 mean in materials such as GS-38.3, GS-52.3...?
In my June1985 edition of DIN 1681 there is no such material name, only without .3.
In Stahlschlussel 2013 there is no such material, only GS-52.3 as a trade name for GS-52.
I found in 20 years old Stahlschlussel edition, that there were some DDR(Deutsche Demokratische Republik) materials with that name, but that is all, I could find.

Customers have materials with .3 on newer drawings, so it is possible, that I have missed some standard.

Anyone?

Percent carbon .3 is 30% carbon

Thank you for your answer. I think, you meant carbon 0.30%.
It is plausible explanation(does it come from any standard?), although in case of low strenght steel like GS-38.3 or GS-45.3 it would make no sense to have carbon more than 0.30%.
