Product Description

APPLICATION:

Steel adjusted for highly loaded parts such as crankshafts of aircraft engines, driving shafts, large-sized turbine components, gear wheels, rotors and discs of steam turbines. Also subject to impact, torsion and vibrations.

TECHNOLOGICAL INFORMATION:

After soft annealing steel becomes machinable ( by improved shearability) and adjusted for the mechanical cutting.

SEMI-FINISHED PRODUCTS:

After soft annealing steel becomes machinable ( by improved shearability) and adjusted for the mechanical cutting.
