Russian Material Equivalent

[Kaplin]

I'm looking for the material properties of a russian material: roct 4543-61 used to make a M72 stud.

Does anyone know either the properties or the North American equivalent to this material?

Thanks

Christine.

Firs of all, the standard you mentioned is 4543-71.

Second – it defines the whole batch of low alloyed steels like 12Õ2Í4À, 15Õ2ÌÀ, 18ÕÃ-Ø, 20ÕÃÍÒÐ-Ø etc. Which one you need?
