Suitable replacement for AISI 8650
Suitable replacement for AISI 8650
(OP)
Hey guys/girls,
I'm having trouble procuring 8650 steel for an item that my company makes, which is a very high-stress part. Not being terribly knowledgeable about materials, is there a suitable replacement for this material? I would prefer to err on the side of caution and substitute a stronger material, if possible.
The item was designed in the 1950s. Was 8650 in more common use at that time? Is there a better material now?
Thanks,
Bill

The part is about 7" long and 1/2" tall. For most of its length it is .200" thick, with the front 1" being .600" thick. So, it is a long, skinny part.
The front 1-1/2" gets through-hardened to around 55 Rockwell C. The remaining 5-1/2" gets through-hardened to around 45 Rockwell C.
The production volume is variable, but let's assume it is around 1,000 parts a year.

Rectangular bars or round bars would both be options. I'm not sure how the the 2 different hardnesses would be attained.
Out of curiosity, how did you determine that 5160 or 4150 would work?
Thanks,
Bill
