PRECISION SHAFTSHARDENING DEPTH(Outer layer depth)Inductively Hardened SurfaceThe hardening depth (hardened outer zone) of the shafts vary according to the shaft diameterand material type. Since the hard outer zone falls off towards the soft core, one speaks of atransition zone subject to a tolerance.The minimum hardening depths are given in the table under "2. Steel Shafts."Example Hardening Curve:70,060,050,0HRC40,030,020,010,00,00,0 0,2 0,4 0,6 0,8 1,0 1,2 1,4 1,6 1,8 2,0 2,2 2,4 2,6 2,8 3,0 3,2 3,4 3,6Outer layer depth [mm]HARD CHROME-PLATED STEEL SHAFTSHard chrome-plated steel shafts are used wherever a highly wear-resistant and rust-proof surfacequality is required for steel shafts, e.g. for piston rods and similar application cases.The chrome layer is galvanically applied and is only a few µm thick. In order to achieve high wearresistance, a hard chrome layer (8 to 15 µm) is applied.The high chromium proportion ensures a particularly high resistance to corrosion.The corrosion protection is only provided by the chromium layer on the cylindrical shell surface. Please notethat the cutting surfaces (frontal faces) and/or the machined shaft segments(e.g. nozzle penetrations, ground surfaces, etc.) have no chromium coating.If the shaft should be completely in a rust-resistant variant, we recommend the use of stainless steel as thebase material.110 MINITEC LINEAR SYSTEM
