The production of these custom long compression springs in 17-7PH material was run at a relatively small batch of only 25 pieces.  17-7PH material was used per AMS 5678 and all production work was done domestically with all secondary processes done with NADCAP certified facilities.  A first article inspection report (FAIR) was provided as well with the parts together with all other certs.  .060 +/-.0015" diameter wire was used to make this part and the ID/OD was set to .78"/.90".  Parts were passivated per AMS 2700, method 1, type 2 or 8 with full certs to complete the production process spanning approximately 7-8 weeks from start.
