I thought I would post here because I respect the opinion of most people that follow this forum on manufacturing and documentation procedures. This issue is not necessarily a GDT or drafting issue directly.
We have been hearing from our purchasing department that our material suppliers are either refusing to give certs for cold worked material, or they are quoting price adders for certs. The price adders can be pretty expensive. Are we being duped, or from your perspective is there a more general trend in the market to either charge (almost exorbitant prices) for certs on cold worked material or not offer them at all? Our people tell us the material vendors tell them they can supply certs for hot rolled/formed material but not for cold worked material. Has anyone else been running into this? Recently we have received some material without a cert, and had it tested and found it to be roughly half the yield strength that it should have been. We have also seen an increase in material received with a cert that is basically fraudulent. Can anyone comment on your experiences? Have you seen a general trend in this regard?
