35、 embrittlement. When tested at the manufacturers recommended concentration in accordance with 4.5.4, neither cadmium plated AISI 4340 steel specimens nor IVD aluminum coated AISI 4340 steel specimens shall exhibit embrittlement. Four specimens of each coating shall be tested using either the sustain

36、ed load procedure or the step load procedure. For the sustained load procedure, embrittlement is indicated if a specimen fractures in less than 200 hours when loaded to 75 percent notched fracture strength. If only one of the four specimens fractures, step load the remaining three specimens at 5 per

37、cent of the notched fracture strength per hour to failure. If these three specimens achieve 90 percent for 1 hour, the chemical shall be considered non-embrittling, For the step load procedure, embrittlement is indicated if a specimen fractures at less than 90 percent of notched fracture strength. 3
