I have a job made out of a material called "custom 455 stainless steel". We had a heat treat op. (heat treat to condition H-1000) done to these parts and we experienced quite a bit of shrinkage on all od diameters and growth on all id diameters. the print says "all dimensions apply before heat treat" but the customer is claiming there is no way these parts could shrink this much. ALL dimensions on the part have changed by .002-.003 total. could someone tell me that this is a possibility. these parts were checked by 4 different people, documented in process, 1st pc, and final inspection before leaving the building. Multiple gaging was used for all dimensions. whats up? thanks.
