30CRMOV9 / 1.7707 STELLA FERRUM

30CrMoV9 ferrum est, qui generatim ad partes extinctas et temperatas fabricandas destinatur, quae plerumque machinantur et postea nitriuntur. Mixtura 30CrMoV9 produci solet ab EAF /VD /LF, deinde electroslag expolitio (ESR) si ad specialem usum necessaria. Vectes et, ubi applicabiles sunt, cudendi examini subiciuntur ultrasonic, secundum diversum gradum secundum exigentias emptorum. Claustra sub condicione vel  subindicato  speciatim  solere subministrantur.
