Bars length: 2m or 3m surface roughness N5-N6

Standard Tolerances
Diameter: ISO h8 (Ø 3-10mm h7)
Length of bars: +/- 30mm
Out of Roundness/eccentricity: 1/2 of diameter

Heat Treatment
Soft annealing: 750-800C slow furnace cooling (2-4 hours)
Hardening: 1000-1050 C
Max obtainable hardness 55 HRC

Cutting Rate
40-55 m/min (approximate value, depending on the lubrication, the cutting tools, the shape of parts)
