VANADIS 10SUB-ZERO TREATMENTPieces requiring maximum dimensional stabilitycan be sub-zero treated as follows:Immediately after quenching the piece should besub-zero treated to between –70 and –80°C (–95 to–110°F), soaking time 1–3 hours, followed by tempering.Sub-zero treatment will give a hardness increaseof ~1 HRC. Avoid intricate shapes as therewill be risk of cracking.NITRIDINGNitriding produces a hard surface layer that increaseswear resistance and reduces the tendencytowards galling.If high temperature tempered VANADIS 10 is normallytempered at 525°C (980°F). This means thatthe nitriding temperature used should not exceed500–525°C (930–980°F). Ion nitriding at a temperaturebelow the tempering temperature used ispreferred.The surface hardness after nitriding is approximately1250 HV 0,2 kg . The thickness of the layershould be chosen to suit the application in question.MachiningrecommendationsThe cutting data below are to be considered asguiding values which must be adapted to existinglocal conditions.TURNINGTurning with carbide TurningCutting data Rough Fine with highparameters turning turning speed steelCutting speed (v c )m/min. 40–70 70–130 10f.p.m. 130–230 230–430 33Feed (f)mm/r 0,3–0,6 –0,3 –0,3i.p.r. 0,01–0,024 –0,01 –0,01Depth of cut (a p )mm 2–6 –2 –2inch 0,08–0,24 –0,08 –0,08Carbide designationISO K15* K15* –* Use a wear resistant Al 2 0 3 -coated carbide grade, e.g.Sandvik Coromant GC 3015 or SECO TP05.DRILLINGHigh speed steel twist drillDrill diameter Cutting speed,v c Feed (f)mm inch m/min f.p.m. mm/r i.p.r.–5 –3/16 8* 26* 0,08–0,20 0,003–0,0085–10 3/16–3/8 8* 26* 0,20–0,30 0,008–0,01210–15 3/8–5/8 8* 26* 0,30–0,35 0,012–0,01415–20 5/8–3/4 8* 26* 0,35–0,40 0,014–0,016* For coated HSS drill v c ≈ 10 m/min.
