Dear all,
We have a cracked 8620 gear which is detected at the end of production line in crack detection.
the parts are supplied in forged&normalized condition.turning,teeth hobbing,spline cold forming takes place in soft condition.the parts are gas carburized and quenched then tempered.after...
Thank you very much for your answers, this really helps.
From the documents these papers seems to evaluate general surface.
Can you please share if there is a spec available for microstructure evaluation for impurities (especially impurities such as SiO2, FeO2 etc) for cast iron (especially...
Hello,
I am searching for the specification max surface imperfections and defects depth (especially impurities such as SiO2, FeO2 etc) for cast iron (especially ductile) automotive powertrain parts.
Unfortunateşy up to now i have not found clear specification.
The part is supplied in cast state...
Dear stanislasdz
you can find the wide answer just from literature(eg. stahlschlussel or ASTM metals hanbook series).But as i understanding you are looking forward to some practical experience. For an application of quenched-tempered bars for automative rear axle commonly Cr-Mo grades are...
Dear Cory/Booker,
Thanks for sharing your experiences.
Do you perform second cycle of induction hardening rework, after intermediate induction temper for austenizin/normalizing

Dear redpicker/bestwrench thanks for your precious comments.As from your answers it seems to be that i need to give further information about the process. The axle half shafts in are induction hardened in our facility.The green shaft material is quenched&tempered condition BS150M36 (close to...
Dear all
I would like to learn about the applicatin of double induction hardening in industry. As far as i know especially when a problem accurs during induction hardening of the shafts(for example the induction operation was interrupted very close to the ending of the cycle due to electricity...
