Custom Aerospace Compression Springs - 17-7PH Stainless Steel Material

We supply these custom aerospace compression springs to our aerospace components manufacturing customer.  17-7PH stainless steel material is used for the domestic production of these parts, per AMS 5673-F.  Our production runs are typically in the smaller 500 piece quantity range for this specific spring, with lead time at 8-10 weeks.  That lead time includes passivation per AMS QQ-P-35, and penetrant inspection per ASTM E 1417 Type I, Method A, Sensitivity L-3.  Each one of those two processes typically takes about 1 week to complete.

Custom Electropolished Springs - 17-7PH Stainless Material

These custom electropolished springs are manufactured domestically for our aerospace customer using 17-7PH material per AMS 5678.  .100" +/- .001" wire diameter is used with an overall free length of 1.355".  Outside diameter is 1.069 +/- .010 and the inside diameter is set at .0869".  Parts had to be heat treated to CH900 per AMS 2759, passivated per AMS 2700 method 1 or method 2, electropolished per PPS 300 Type III, and go through magnetic particle inspection per ASTM E1444.

Custom .250 Wire Compression Springs - 17-7 Stainless Steel Material

We supplied 100 pieces of these 2.87" free length custom .250 wire compression springs to our aerospace customer with a first article inspection report (FAIR), MIL-STD-6866 dye penetrant inspection report (Type 1, Method A, Sensitivity Level 3), heat treat certs, and a certificate of conformance.  The outside diameter is 1.218 +/- .010" and the inside diameter is .718".  Heat treat was done to condition CH900 per MIL-H-6875.  Production was done domestically with a rush option to help our customer get out of a timing jam.
