  1. CoC 968146:
    FPI: 32 parts inspected instead of 200 (ISO2859-1, AQL = 0,065%, normal inspection, single sampling).
    However, ISO2859-1 sampling issue has been raised subsequently to the manufacture of this lot number.
    LISI AEROSPACE’s sampling interpretation agreement was obtained in April 2019.
    Hardness test: hardness value range written is 11 to 45 HRC.
    EN2583 requires a range from 36 to 45 HRC.
    Salt spray test (Acceptance): EN2583 requires 100% inspection for this test whereas 3 bolts were tested.
    I would like to get Auditor’s and mfg’s feedback on this topic since, from my point of view, using bolts that have undergone Salt spray test (Acceptance) may be inappropriate even if exposure duration is quite short.

    Hardness test: could you please give us hardness values in HRC units?

    Many thanks in advance,
    Regards.

    1. All batches were manufactured before June 2019. In LISI AEROSPACE’s sampling interpretation agreement we said that we will comply with this interpretation from June 2019.
      Coc 968146 Hardness test : It’s a typo error, 11 to 45 HRC instead of 44 to 45 HRC.
      CoC 952646, 470670 and 929188 : the salt spray test is carried out in process follow-up.
      CoC 935133 : by conversion the hardness is between 44.5 and 45.3 HRC.

  2. Thank you for replying.
    For mfg batch 935133, the highest HRC value is just above the upper limit (45 HRC).
    Which hardness conversion table has been used? (ASTM A370? ISO 18265? Another one?)
    Best regards.

  3. So, maximum converted HRC value is just above the limit, but out of tolerance according to EN2583 (from 36 to 45 HRC).
    ISO18265 table A1 (Conversion of hardness-to-hardness or hardness-to-tensile-strength values for unalloyed and low alloy steels and cast steel) is a conversion from HV10 into HRC and LISI performed HV30.
    These bolts are in Inconel 718, so, risk of embrittlement is (really) low from my point of view, compared to low-alloyed steels.
    Nevertheless, since these bolts are made of Inconel 718, ISO18265, table 7 may be more appropriate.
    Finally, converted HRC value is just above the upper limit and hardness conversion is always sensitive, interpretable.
    Moreover, all other mechanical and metallurgical tests are compliant.
