Mechanical Properties: The linear shafts are hot rolled according to DIN 17212: 1972 standards. They exhibit a tensile strength (R) between 610 - 760 N/mm², a yield strength (Rp 0.2) of at least 340 N/mm², an elongation (A%) of at least 16%, and a Brinell hardness (HB) ranging from 183 to 226.

Chemical Composition: The chemical analysis of the shafts includes Carbon (0.50 - 0.57%), Silicon (0.15 - 0.35%), Manganese (0.40 - 0.70%), Phosphorus (max 0.025%), and Sulfur (max 0.035%). Tolerances for these elements are ±0.03 for C, Si, and Mn, and +0.005 for P and S.

Dimensional Specifications: The shafts are available in diameters ranging from 6 mm to 100 mm, with corresponding weights from 0.23 Kg/m to 61.62 Kg/m. Lengths vary between 6000 mm and 6500 mm, depending on the diameter. Surface hardness is consistent at 62 - 64 HRC, with a hardening depth between 0.6 mm and 4.5 mm. Straightness is maintained at a maximum of 5 mm/m, and roundness and conicity are controlled to a maximum of 5 μ.

Surface Finish: The surface finish is specified at 0.20 - 0.25 μ RA, ensuring a smooth and precise finish suitable for various applications.

Manufacturing Program: The shafts are available as hardened chromed shafts with a chrome thickness of 8/15 μ, adhering to ISO h6 tolerance. The chrome film hardness is between 950 and 1100 HV.
