Product Description

APPLICATION:

Steel susceptible to the parts averagely exposed on loadings and more resistant to abrasion. For the parts such as: axles, crankshafts, spindles, discs, pump rotors, etc.

TECHNOLOGICAL INFORMATION:

After soft annealing, steel becomes machinable; if normalised and soft annealed, steel becomes adjusted for the mechanical cutting.

SEMI-FINISHED PRODUCTS:

After soft annealing, steel becomes machinable; if normalised and soft annealed, steel becomes adjusted for the mechanical cutting.
