The purity grade of the X2CrNiMnMoNNb23.17.6.3 forged steel material is to be determined per DIN 50602-K1.The following value is to be kept in this case(on 1000 mm²)-Sum characteristics value K1:≤2.0
For determination 4 tests per heat are to be employed at least Depending on the appearance of the analysed microsections also higher K1-Values may possibly be Tolerated.Content of Delta-Ferrite Delta ferrite content:<5% (Determined in a manner consistent with the evaluation technique described in ASTM E 45/Method A,"Worst Field Method"at V=100,specimen orientation:longitudinal.Thedistribution and size of delta ferrite must be such that it does not result in indication in magnetic particle testing of the ready-machined surface.)
