About the sound
The sound of steel hardening after pilgrim rolling.
After the termination of pilgrim rolling, certain alloys have to be air-cooled in steps based on rolling speed parameters.

Their range of products includes ingots, billets with rounded edges and wide flats, with round, flat and square sections, forged bars, machined forgings, discs, bushes, etc.
