Fig. 62 Comparison of oil quenching in a batch and single-piece quenching in a gas nozzle field. Source: Ref 34 More

Fig. 2(a) Front view of an AISI O1 tool steel die that cracked during oil quenching. The die face contains holes that are too close to the edge for safe quenching. See also Fig. 2(b) . 0.6× More

Fig. 3 AISI O1 tool steel die that cracked during oil quenching. Note the cracks emanating from the sharp corners. The four holes, which are close to the edge, also contributed to cracking. Temper color was observed on the crack walls. More

Fig. 4 Fixture made from AISI O1 tool steel that cracked during oil quenching. This design is poor for liquid quenching. A nick in the fillet region helped to initiate cracking. 0.75× More
