I am dealing with a supplier who wants to grind away the visible indications of a "cold shut" on steel castings that they supply to us. Our customers specifications say that "cold shuts" are unacceptable for any reason. The supplier wants to avoid scrapping hundreds of parts. My concern is that a "cold shut" is likely more of a defect than a visual defect. I believe it weakens the casting, and that grinding away the visual effect would only disguise the fact of a compromised casting.
Am I wrong? Is the supplier suggesting something reasonable? I am a machinist by trade, and an engineer by default, not a metallurgist. I need expert advice from someone who really knows their steel castings.
