Hardness testing was performed on 1 sample each of parts TBP1822 and TBP1823 (part of the 35-deg magnet stand assembly TBP1804),  They were found to be 60-60.5 Rc and 60-61 Rc respectively which is within spec.  The alloy used to fabricate these parts was AISI #8620. The testing was performed by Precision Heat Treat in Surrey who also performed the heat treatment at an earlier date.
