Inquiry (采购产品): Material specs We have at our facility 3 sets of Titanium Distance/Amplitude blocks purchased from PH tool in December of 1992. I have on file the certification report per ASTM E428. But I am in need of a statement of compliance to AMS 4928. The heat number for each set is D91213 and the PO # is 344358.
