What is exactly CFS?
What is exactly CFS?
(OP)
Could any one please tell me what is CFS?
I submitted a PPAP for a screw machine part and the customer rejected it. The reason for rejection is, the material on the drawing is CFS and I used 12L14. They are saying that material cert doezn't match the spec. I think CFS is a very broad range and we can use any steel as long as it is cold worked, right?
Thanks.

I would change the print to to allow the 12L14 material as it's one of the best, fastest, for screw machine parts.
