The subject says it all. Can anyone in our group give me the AISI or ASTM equivalent of this British Standard Steel.

I am pretty sure that it was originally a plate steel that was rolled into a cylinder, fabricated into a quarter or half section of a large ring gear, normalized or at least stress relieved, it was probably re-heat treated to achieve an internal hardness of approximately 325 Brinnel and then had helical gear teeth cut into it.

Any help would be greatly appreiciated.

Thanks,

Well, I have to apologize to the group. After getting home and doing some research I see that BS 3100 is "Steel castings for General Engineering Purposes" and the Bt2 is an error on the part of the people posing the qustion to me.

They will have to provide me with more information, obviously.

Thanks,
