... it is possible to crack hardened type 440C during the chromium plating process. An inspection for pitting on the bearing inner diam was also recommended. It was suggested that electroless nickel be used as a coating for the entire bearing. A review of the chromium plating and baking sequence was recommended also...

... embrittlement. The fasteners failed in a brittle manner as the result of hydrogen embrittlement. Hydrogen was induced into the surface of the steel when the hardened parts were acid cleaned before electroplating and during the electroplating operation. Baking at 165 °C (330 °F) for 8 h failed to remove all...
