Description For applications where corrosion resistance and cleanliness are critical, e.g., in the food industry, semiconductor production and medical equipment. Product description The right choice for applications where corrosion resistance and cleanliness are critical, e.g., in the food industry, semiconductor production and medical equipment. X 90 CrMoV 19 is more resistant to lactic acid than X 46 Cr 13. Technical data Dimensional accuracy and tolerance zones The diameters of the precision steel shafts come in h6 and h7 tolerance zones. The adjacent table shows information on dimensional accuracy. The diameter tolerance of annealed shaft cross-sections vary slightly from the specified tolerance zone.

Straightness is measured based on ISO 13012. Measurement of straightness based on ISO 13012 The measuring points are evenly distributed between the support points and the shaft sections protruding past them. More supports are used accordingly for long, thin shafts. Straightness is half of the gauge measurement when turning the shaft 360°. Measurement of roundness The drawing shows the roundness of a raw shaft compared to a precision steel shaft. a) Raw shaft b) Precision shaft Shaft hardness The outer zone of the shaft is induction-hardened. Depending on the shaft diameter, the depth of hardness ranges from 0.4 to 2.4 mm. Linear and transverse surface hardness and depth of hardness are highly consistent. This ensures high dimensional consistency and long service life. The adjacent figure shows the cross-section and longitudinal section of a hardened and polished precision steel shaft. The hardened surface zone is made visible by caustic etching.
