SAE 4130
SAE 4130
(OP)
I am currently trying to reproduce an old Westinghouse part from the 70's that was made using SAE 4130 steel, heat treated, w/ 42 HRC (per print). Now I'm learning from vendors that this SAE 4130 steel is hard to come by now a days and that S7 is a good replacement. This doesn't seem right, am I missing something?

I don't know what size you require, but it is available.

One other thing it would be helpful to know is exactly what material form, size and specification did you use on your PO? You mentioned this material was for a Westinghouse legacy part. It is quite common for large OEMs to use their own specs when procuring raw materials. Are you trying to procure 4130 that must conform to a Westinghouse specification?
