(1920°F/30 min.) followed by gas quenching in a coldchamber vacuum furnace.Specimen size: 65 x 65 x 65 mm (2,5" x 2,5" x 2,5" )Austenitizing temperature 1050°C (1920°F)SUB-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.The tempering temperature should be lowered25°C (50°F) in order to get the desired hardnesswhen a high temperature temper is performed.Sub-zero treatment will give a hardness increaseof ~1 HRC. Avoid intricate shapes as therewill be risk of cracking.For the highest demands of dimensional stabilitysub-zero cooling in liquid nitrogen is recommendedafter quenching and each tempering.Dimensional changes %+0,10+0,08▲525°C(980°F)+0,06+0,04+0,020–0,02–0,04Temperingtemperature200°C(390°F)L T SL T S–0,06–0,08L =Length, T =Transverse, S =Short transverseParts blanked in a VANADIS 6 tool from AllenvaleTools & Production Ltd., Great Britain.6
