Popis:	1. Under existing standards the heating rates in heat treatment are attained with fairly even heating and minimal thermal stresses in both hollow and solid propeller shafts (diameter up to 600 mm) of steel 34KhN1M. Both types of shafts are hardened throughout the section by quenching in water. 2. In terms of mechanical properties, cold brittleness threshold, fatigue limit, and microstructure the shafts with a center hole have no substantial advantage over solid shafts. Thus, the necessity of drilling center holes in forgings of steel 34KhN1M for shafts up to 600 mm in diameter is doubtful.
