Razz ne znam baš da to tako ide....jedino sam ZDP vidio da se prodaje zakaljen i to mi je bilo
ono čudno ali koliko se sjećam ponuđena je bila opcija okaljen i ne okaljen Shocked
I to je to ...jedan i rijedak primjer.
Ali ne kužim...poantu, uostalom  ok grindanje zakaljenog čelika na već donekle obrađeenom
blanku ali komplet brušenje? nije i ovaj post HT za svakoga baš Cool

Zasto ne ? Ako mogu kermikom brusiti HSS koji je pun carbida ko moj pas buha , zasto ne bih mogao S90V , M390  . .. .. .Very Happy Nemam mogucnosti da kalim te praskaste ovde . Kupis parce vec HT celik duzine i debljine koja ti treba , izrezes blank i grindaj brate . Kada zavrsim novi grinder ti praskasti ima da bjeze kada ga cuju kako im reze zubima Very Happy

Nije frka sa grejanjem .HSS je bezbedan sve do 550 stepeni ..............a to je nomoguca misija dok grindam da se desi ..........U stvari ne prelazi ni 60 stepeni , posto non stop imam kontakt ...........

Isto recimo S90V
pogledaj tempering podatke za njega ..........IHA -HA  Very Happy

Hardening: Austenitize: 2100-2150°F (1150-1175°C) Hold time at temperature: 10-30 minutes Quench: Salt quench, interrupted oil quench, positive pressure gas quench or air cool at a minimum cooling rate of 150°F/min (80°C)/min) to below 1000°C (540°C) followed by still air or moderately forced air cooling to below 125°F (50°C). For optimum vacuum heat treatment response, a minimum 4 bar gas quench is recommended. Temper: For an optimum combination of hardness, wear resistance and corrosion resistance, double temper at 400-750°F (200-400°C). Hold for a minimum of 2 hours each temper. For optimum stress relieving and dimensional stability, S90V may be double tempered at 1000-1025°F (540-550°C), but tempering above 800°F (425°C) may result in some loss of corrosion resistance. A freezing treatment may be employed between the first and second tempers, if desired. Freezing treatments should always be followed by at least one temper. wrote:

Jašta svašta Razz  komad zakaljenog M390 250x40x4mm 120$ bez shipping i ostala davanja Rolling Eyes
usporedi s cijenom u EU nezakaljenog...4,3x40x1200mm 150.00 € + 25€ shipping 
i to da je recimo usluga kaljenja cca 15€ po blanku za 250mm dužine.
