Do we have a chance to get some information about stress relief before cadmium plating and hydrogen embrittlement relief after cadmium plating?
In QTS, for double shear test, it is written “Pass”, “Conform to ISO7689”.
EN3035 clause 6.3 states that double shear test is deleted.
Thus, from my point of view, it is preferable to write that this test is not applicable as per EN3035, clause 6.3. This is just something to point out and not blocking.
Many thanks in advance,
Best regards.
=> Stress relief was done for 4 hours at 190.8 °C before cadmium plating.
=> De embrittlement was done during 52 hours at 191 °C after cadmium plating.
=> QTS has been updated. The double shear test is noted not applicable in the QTS enclosed.
Many thanks for these updates and answers!
Approved on my side.
Best regards.
