I had an enquiry from a customer to make end flanges used in autombile exhaust system. This has a DIN number(Equivalent to AISI 304) which I do not remember now. This is for Europe market. Originally this is being made as a forging but now it is intended to convert it into a casting due to cost considerations. This is a small flange about 150 mm OD and ID 130 mm and 10-12 mmthick. The finished weight is 650 grams. Quantities are 15000 peces/month.
My question is will the inspector accept a cast product. As I see the service conditions are not too severe and CF8 casting should well serve the purpose.
